Abstract
This study was a first analysis of paternal genetic diversity for extensive Asian domestic goats using SRY gene sequences. Sequencing comparison of the SRY 3'-untranslated region among 210 Asian goats revealed four haplotypes (Y1A, Y1B, Y2A and Y2B) derived from four variable sites including a novel substitution detected in this study. In Asian goats, the predominant haplotype was Y1A (62%) and second most common was Y2B (30%). Interestingly, the Y2B was a unique East Asian Y chromosomal variant, which differentiates eastern and western Eurasian goats. The SRY geographic distribution in Myanmar and Cambodia indicated predominant the haplotype Y1A in plains areas and a high frequency of Y2B in mountain areas. The results suggest recent genetic infiltration of modern breeds into South-East Asian goats and an ancestral SRY Y2B haplotype in Asian native goats.

Abstract
The domestic goat is one of the most important livestock species, but its origins and genetic diversity still remain uncertain. Multiple highly divergent maternal lineages of goat have been reported in previous studies. Although one of the mitochondrial DNA lineages, lineage B, was detected only in eastern and southern Asia, the geographic distribution of these lineages was previously unclear. Here, we examine the genetic diversity and phylogeographic structure of Asian goats by mitochondrial DNA sequences and morphological characteristics. The analyses of a total of 1661 Asian goats from 12 countries revealed a high frequency of lineage B in Southeast Asia. The frequency of this lineage tended to be higher in mountain areas than in plain areas in Southeast Asian countries, and there was a significant correlation between its frequency and morphological traits. The results suggest an original predominance of lineage B in Southeast Asia and the recent infiltration of lineage A into Southeast Asian goats.

Abstract
We sequenced the 16S rRNA gene in mitochondrial DNA to characterize mithun located in Bhutan and to increase our understanding of its origin. We compared mithun with yak, European cattle, Bhutanese zebu and Indian zebu. Sequencing revealed low nucleotide diversity within the mithun population and their phylogenetic proximity to gaur. A close relationship between Bhutanese mithun and gaur was confirmed by an additional comparison with wild gaur specimens from three locations in Bhutan. Direct domestication of mithun from gaur was supported, while maternal contribution from the cattle lineage during domestication was not supported.

Abstract
In Japan, Japanese Black and Holstein cattle are appreciated as popular sources of meat, and imported beef from Australia and the United States is also in demand in the meat industry. Since the BSE outbreak, the problem of false sales has arisen: imported beef has sometimes been mislabeled as domestic beef due to consumer concerns. A method is needed to correctly discriminate between Japanese and imported cattle for food safety. The objective of this study was to develop breed discrimination markers between Japanese and US cattle using a 50K SNP array. As a result, five US-specific markers (BISNP7, BISNP15, BISNP21, BISNP23, and BISNP26) were developed with allelic frequencies that ranged from 0.102 (BISNP15) to 0.250 (BISNP7) and averaged 0.184. The combined use of the five markers would permit discrimination between Japanese and US cattle with a probability of identification of 0.858. This result indicates the potential of the bovine 50K SNP array as a powerful tool for developing breed identification markers. These markers would contribute to the prevention of falsified beef displays in Japan.

Abstract
Stearoyl-CoA desaturase (SCD) catalyzes the synthesis of monounsaturated fatty acids (MUFAs). In cattle, the MUFAs are related to softness and flavor of meat. In order to investigate gene expression profile during bovine preadipocyte differentiation, we isolated stromal-vascular cells from perirenal adipose tissues of Japanese Black and Holstein steers. Gene expression level of adipocyte type fatty acid binding protein (FABP4), SCD, sterol regulatory element binding protein 1 (SREBP1) and CCAAT/enhancer binding protein alpha (C/EBP-alpha) were elucidated by real-time PCR assay. The levels of SCD mRNA expression were significantly increased to 10.8 and 6.3-fold in Japanese Black and Holstein, respectively, on day 1 of the culture. The difference in SCD expression between the two breeds may reflect differences in the fat development characteristics of the cattle breeds. Although transcription factors SREBP1 and C/EBP-alpha are supposed to regulate SCD expression, expression levels of the two factors were not completely consistent with that of SCD.

Abstract
In order to develop a comparative map between chicken and quail, we identified orthologous gene markers based on chicken genomic sequences and localized them on the Japanese quail Kobe-NIBS linkage map, which had previously been constructed with amplified fragment length polymorphisms. After sequencing the intronic regions of 168 genes located on chicken chromosomes 1-8, polymorphisms among Kobe-NIBS quail family parents were detected in 51 genes. These orthologous markers were mapped on eight Japanese quail linkage groups (JQG), and they allowed the comparison of JQG to chicken macrochromosomes. The locations of the genes and their orders were quite similar between the two species except within a previously reported inversion on quail chromosome 2. Therefore, we propose that the respective quail linkage groups are macrochromosomes and designated as quail chromosomes CJA 1-8.

Abstract
The Japanese quail (Coturnix japonica) is a notably valuable egg and meat producer but has also been used as a laboratory animal. In the present study, we constructed a Japanese quail linkage map with 1735 polymorphic amplified fragment length polymorphisms markers, and nine chicken microsatellite (MS) markers, as well as sex and phenotypes of two genetic diseases; a muscular disorder (LWC) and neurofilament-deficient mutant (Quv). Linkage analysis revealed 578 independent loci. The resulting linkage map contained 44 multipoint linkage groups covering 2597.8 cM and an additional 218.2 cM was contained in 21 two-point linkage groups. The total map was 2816 cM in length with an average marker interval of 5.5 cM. The Quv locus was located on linkage group 5, but linkage was not found between the LWC locus and any of the markers. Comparative mapping with chicken using orthologous markers revealed chromosomal assignments of the quail linkage group 1 to chicken chromosome 2 (GGA2), 5 to GGA22, 2 to GGA5, 8 to GGA7, 27 to GGA11, 29 to GGA1 and 45 to GGA4.

Abstract
In order to clarify the origin and genetic diversity of cattle in North Eastern Asia, this study examined mitochondrial displacement loop sequence variation and frequencies of Bos taurus and Bos indicus Y chromosome haplotypes in Japanese, Mongolian, and Korean native cattle. In mitochondrial analyses, 20% of Mongolian cattle carried B. indicus mitochondrial haplotypes, but Japanese and Korean cattle carried only B. taurus haplotypes. In contrast, all samples revealed B. taurus Y chromosome haplotypes. This may be due to the import of zebu and other cattle during the Mongol Empire era with subsequent crossing with native taurine cattle. B. taurus mtDNA sequences fall into several geographically distributed haplogroups and one of these, termed here T4, is described in each of the test samples, but has not been observed in Near Eastern, European or African cattle. This may have been locally domesticated from an East Eurasian strain of Bos primigenius.

Abstract
Japanese Black cattle are characterised by a unique ability to deposit intramuscular fat with lower melting temperature. In this study, 3 consecutive biopsies from Longissimus muscle tissue were taken and RNA isolated from 3 Japanese Black (Tajima strain) and 3 Holstein animals at age 11–20 months. The gene expression changes in these samples were analysed using a bovine fat/muscle cDNA microarray. A mixed-ANOVA model was fitted to the intensity signals. A total of 335 (4.8%) array elements were identified as differentially expressed genes in this breed × time comparison study. Genes preferentially expressed in Japanese Black are associated with mono-unsaturated fatty acid synthesis, fat deposition, adipogenesis development and muscle regulation, while examples of genes preferentially expressed in Holstein come from functional classes involved in connective tissue and skeletal muscle development. The gene expression differences detected between the Longissimus muscle of the 2 breeds give important clues to the molecular basis for the unique features of the Japanese Black breed, such as the onset and rate of adipose tissue development, metabolic differences, and signalling pathways involved in converting carbohydrate to lipid during lipogenesis. These findings will impact on industry management strategies designed to manipulate intramuscular adipose development at different development stages to gain maximum return for beef products.

Abstract
Our previous studies revealed that the genetic locus for chicken muscular dystrophy of abnormal muscle (AM) mapped to chromosome 2q, and that the region showed conserved synteny with human chromosome 8q11-24.3. In the current study, we mapped the chicken orthologues of genes from human chromosome 8q11-24 in order to identify the responsible gene. Polymorphisms in the chicken orthologues were identified in the parents of the resource family. Twenty-three genes and expressed sequence tags (ESTs) were mapped to chicken chromosome 2 by linkage analysis. The detailed comparative map shows a high conservation of synteny between chicken chromosome 2q and human chromosome 8q. The AM locus was mapped between [inositol(myo)-1(or4)-monophosphatase 1] (IMPA1) gene and [core-binding factor, runt domain, alpha-subunit 2; translocated to 1; cyclin D-related] (CBFA2T1) gene. The genes located between IMPA1 and CBFA2T1 are the most likely candidates for chicken muscular dystrophy.

Abstract
On the basis of sequence variation in the displacement loop region of mtDNA, 588 Japanese and North American Holstein cows were classified into 5 mitochondrial haplotypes, which were found in Japanese Black cattle. One of the haplotypes (named type 1), which was present at the highest frequency in Japanese Black cattle, was not observed in either European or African cattle. This haplotype is characterized by 2 single-nucleotide polymorphisms. One is called the type B polymorphism, and it refers to a base change from T to C at nucleotide 16042 of the mitochondrial genome (T160042C). The other is called the type I polymorphism, and it refers to the base change as G16093A. The proportion of the Japanese Holstein population with both polymorphisms was 18.3%, whereas none of the North American cows had this genotype. Because the mitochondrial types were inherited maternally, it is clear that a considerable number of Japanese Holstein cows are descended from native Japanese cattle. Polymorphisms B and I accounted for no variance in the estimated breeding value for milk production among cows from the Hyogo herd (582 cows) or the Chiba region herd (758 cows). This result suggests that most autosomal genes of native animals have been successively replaced by those of pure Holstein after grading up of over 15 generations, even though resulting animals have native animal-oriented mitochondrial types and may still have some number of the native autosomal genes.

Forty-eight cows with extreme genetic merit for beef marbling score (BMS) were selected from a population of Japanese Black cattle (n = 4462), including 25 with the highest for predicted breeding value (PBV) and 23 with the lowest. Sixteen AFLP fragments were selected for further analysis based on fragment frequency differences between the high and low groups. A linear discriminant analysis using these AFLP fragments was applied in order to derive a discriminant function that classified the cows into high and low groups. Seven of the 16 fragments were included in the resulting function and the discriminant scores (general genetic values, GGV) of the 48 cows were calculated using the function. These cows were clearly separated into high and low groups by GGV with a correlation ratio of 0.91 (discriminative error of 2.1%). The same function was then applied to 121 additional cows that were randomly selected from the original population. A significant regression coefficient of GGV on BMS-PBV (R2 = 0.45) was obtained, which indicates that the GGV can be used as a selection criterion for BMS in this population. These results suggest that AFLP fingerprinting can be used for animal breeding without identifying the underlying genes affecting the trait of interest.

Abstract
Pakistan contains numerous domestic goat breeds, but until now there has been no comprehensive study on genetic diversity or a phylogenetic analysis of Pakistani goats. In this study, we analysed the complete mitochondrial DNA D-loop and the cytochrome b gene of 13 Pakistani domestic goat breeds (Capra hircus) and one wild goat, the Sindh Ibex (Capra aegagrus blythi). The phylogenetic analyses and sequence divergence (SD) established four distinct mt-lineages termed as A, B and C (previously reported) and a new lineage D. The Sindh Ibex appeared as an outgroup of domestic goats. The estimated divergence times between the most recently evolved mt-lineages A and D were from 260,483 to 371,052 YA. This suggested that at least four different strains of wild Capra might have been the source of the modern domestic goats. The new mt-lineage D revealed high SD from mt-lineage A and may be the oldest branch under domestication, while mt-lineages B and C showed lower SD and might have been domesticated during an advanced stage of the domestication process.

Abstract
Complete sequences of mitochondrial (mt) genomes of eight Japanese Black cattle were determined to investigate the relationships between mt deoxyribonucleic acid (DNA) displacement loop (D-loop) types and other mtDNA regions and to identify the variation in the coding region that may influence the economic traits. The survey of mitochondrial sequences in the encoding region revealed 14 substitutions including six antonymous substitutions and one in 16S ribosomal ribonucleic acid (rRNA). Three methods of polymorphic DNA analyses (polymerase chain reaction [PCR]-restriction fragment length polymorphism [RFLP], mismatch PCR-RFLP, PCR-single-strand conformation polymorphism [SSCP]) were performed on these seven candidate substitutions (base pair [bp] 2,232, 12,158, 12,908, 13,310, 14,122, 14,140, and 14,565) for 202 Japanese Black cattle. The substitution of bp 13,310 was observed in all samples, but not in the reference sequence, indicating that this is a minor substitution or a sequencing mistake in the reference sequence. The substitutions at bp 14,122, 14,140, and 14,565 were observed in only a few samples, suggesting that these were also minor substitutions. The substitutions at bp 2,232 (16S rRNA), 12,158, and 12,908 (reduced nicotinamide adenine dinucleotide-ubiquinone oxidoreductase chain-5) were closely related to mitochondrial D-loop types that have previously been related to differences in the carcass traits of Japanese Black cattle. Evaluation of the effects on six carcass traits with mixed model procedures suggests that the bp 2,232 substitution affects longissimus muscle area and beef marbling score. The substitution at bp 2,232 is a strong candidate for the mitochondrial effect on meat quality.

Abstract
A chicken linkage map, constructed with the Kobe University (KU) resource family, was used to locate the genetic locus for muscular dystrophy of abnormal muscle type (AM). The KU resource family is a backcross pedigree with 55 offspring produced from the mating of a White Leghorn F-line (WL-F) male and a hybrid female produced from a cross between the WL-F male and a female of the Fayoumi OPN line who was homozygous for the AM gene. In total, 872 loci were genotyped on the pedigree; 749 (86%) were informative and mapped to 38 linkage groups. These informative loci included 649 AFLPs, 93 MS, three functional genes, the AM locus, sex phenotype, and two red blood cell loci. The remaining 123 markers were unlinked. Nineteen of the 38 KU linkage groups were assigned to macrochromosomes 1-8 and 11 microchromosomes including chromosome W, while 19 linkage groups were unassigned. The total map was 3569 cM in length, with an average marker interval of 4.8 cM. The AM locus was mapped 130 cM from the distal end of chromosome 2q.

Abstract
This article describes the complete sequences of the mitochondrial DNA displacement loop (D-loop) region and cytochrome b gene from domestic goats in Laos (Laos native) and wild goat "markhor" (C. falconeri). The wild goat "bezoar" (Capra aegagrus) has been considered to be the strongest candidate for the ancestor of the domestic goats (C. hircus); however, there is not sufficient molecular data to verify the hypothesis at present. In phylogenetic analyses, two wild goats, the markhor and the ibex (C. ibex), appeared as an outgroup, while the bezoar was located in a cluster of domestic goats. Mitochondrial haplotypes of Laos natives revealed two distinct major clusters: one was the same as the bezoar, the second, unique to Laos natives. The topology and calibrated levels of sequence divergence suggests that these clusters might represent at least two different subspecies of ancestral bezoars.

Abstract
Pig testicular lactate dehydrogenase-C (LDHC) cDNA was cloned and sequenced. The deduced sequence of 332 amino acids from pig LDHC shows 73% and 67% identity with that of pig LDHA (muscle) and LDHB (heart) respectively, whereas pig LDHA and LDHB isozymes shows 74% sequence identity. Pig and mouse LDHC cDNAs were subcloned into bacterial expression vector, and the expressed pig LDHC isozyme was shown to be as thermally stable as mouse LDHC isozyme. Pig genomic DNAs from Chinese Meishan, English Yorkshire, Danish Landrace and American Duroc were shown to exhibit polymorphic sites for restriction enzymes EcoRI, BamHI and PstI.

Abstract
Although turtles have been generally grouped with the most primitive reptile species, the origin and phylogenetic relationships of turtles have remained unresolved to date. To confirm the phylogenetic position of turtles in amniotes, we have cloned and determined the cDNA sequences encoding for skink lactate dehydrogenase (LDH)-A and LDH-B, snake LDH-A, and African clawed frog LDH-A; four alpha-enolase cDNA sequences from turtle, alligator, skink, and snake were also cloned and determined. All of these eight cDNA sequences, as well as the previously published LDH-A, LDH-B, and alpha-enolase of mammals, birds, reptiles, and African clawed frog, were analyzed by the phylogenetic tree reconstruction methods of neighbor-joining, maximum parsimony, and maximum likelihood. In the phylogenetic analyses, the turtle was found to be closely related to the alligator. Also, we found that the turtle had diverged after the divergence of squamates and birds. This departs from previous hypotheses of turtle evolution and further suggests that turtles are the latest of divergent reptiles, having been derived from an ancestor of crocodilian lineage within the last 200 million years.

Abstract
Mouse SMT3A and SMT3B cDNAs encoding ubiquitin-like proteins of 110 and 95 amino acids, respectively, were isolated and sequenced. The sequence of the first 92 amino acids (ending with the conserved Gly-Gly) of mouse SMT3A exhibited two differences at amino acid no. 38 and 76 in comparison with that of human SMT3A. The C-terminal 18 amino acid sequence of mouse SMT3A was completely different from the C-terminal 11 amino acid sequence of human SMT3A. Mouse and human SMT3B were identical for a sequence of 95 amino acids. Mouse SMT3A genomic DNAs were amplified by polymerase-chain-reaction and sequenced. The nucleotide sequence of a PCR-amplified SMT3A genomic DNA fragment was found to be identical to that of SMT3A cDNA, indicating the absence of intron(s) in its protein coding region. Another genomic DNA fragment of 1,531 nucleotides, containing 7% differences from that of cDNA, is unable to encode a functional protein, and thus, it is a SMT3A processed pseudogene. Three mouse SMT3B processed pseudogenes were cloned and sequenced. The genuine mouse SMT3B gene has not yet been isolated. Mouse SMT3A transcript of 1.8 kb was predominantly expressed in most tissues, while SMT3B transcript of 1.0 kb was abundantly present in all tissues analyzed. A family of ubiquitin-like proteins was recently discovered. One distinguishing feature of ubiquitin and ubiquitin-like proteins is the capacity to conjugate with other proteins post-translationally. The ubiquitin-like proteins are cleaved endoproteolytically after a diglycine sequence, corresponding to the C-terminal Gly75-Gly76 of ubiquitin. The cleavage activates the molecule for conjugation. The yeast SMT3 gene was originally identified as a suppressor of mutations in MIF2 gene, which encodes an essential protein binding to the A+T-rich CDEII region of centromere DNA (1). Studies using temperature-sensitive mutants showed that the loss of yeast Mif2 protein function results in chromosome missegregation, mitotic delay, and aberrant microtubule morphologies (2). The yeast Mif2 protein shares at least two regions of similarity with mammalian centromere protein CENP-C, an integral component of active kinetochores (3, 4). Human SMT3A cDNA was identified from the genome sequencing project of chromosome 21 (5). We have cloned human SMT3B (formerly designated as HSMT3) cDNA (6). Human SMT3C protein was independently isolated by several groups and denoted as SUMO-1 (7), GMP1 (8), PICI (9), UBL1 (10), sentrin (11). SUMO-1/GMP1 was found to be covalently linked to the Ran GTPase-activating protein RanGAP1, and attachment of SUMO-1 targets the otherwise cytosolic RanGAP1 to the nuclear pore complex. The modified form of RanGAP1 also appeared to associate with the mitotic spindle apparatus during mitosis (7, 8). PIC1 was shown to interact with the PML component of nuclear multiprotein complex that is disrupted in acute promyelocytic leukemia (9). UBL1 was found to associate with human RAD51/RAD52 proteins involved in DNA recombination and DNA double-strand break repair (10). Sentrin was shown to interact with Fas/APO-1 or the TNF receptor 1 death domain, and the overexpression of sentrin provided protection against both anti-Fas/APO-1 and TNF-induced cell death (11). Here we report the characterization of mouse SMT3A and SMT3B cDNAs, gene/pseudogenes, and mRNA expression.

Abstract
This article describes complete mitochondrial DNA displacement loop sequences from 32 Japanese Black cattle and the analysis of these data in conjunction with previously published sequences from African, European, and Indian subjects. The origins of North East Asian domesticated cattle are unclear. The earliest domestic cattle in the region were Bos taurus and may have been domesticated from local wild cattle (aurochsen; B. primigenius), or perhaps had an origin in migrants from the early domestic center of the Near East. In phylogenetic analyses, taurine sequences form a dense tree with a center consisting of intermingled European and Japanese sequences with one group of Japanese and another of all African sequences, each forming distinct clusters at extremes of the phylogeny. This topology and calibrated levels of sequence divergence suggest that the clusters may represent three different strains of ancestral aurochs, adopted at geographically and temporally separate stages of the domestication process. Unlike Africa, half of Japanese cattle sequences are topologically intermingled with the European variants. This suggests an interchange of variants that may be ancient, perhaps a legacy of the first introduction of domesticates to East Asia.

Abstract
Ornithine transcarbamylase (OTC) is one of the urea cycle enzymes. While the chicken is a uricotelic animal, it has measurable OTC activity in its kidney. OTC activity is highly variable within and between chicken breeds. Chicken OTC may have some physiological significance because of its significant activity in the kidney. We cloned the OTC cDNA from chicken kidney and found 77% homology between the deduced amino acid sequence of the mature protein and that of mammals. The chicken OTC gene spans 26 kb, consists of 10 exons and 9 introns, and utilizes the same exon-intron boundaries as the human gene. The 5'-flanking region contains a putative TATA box and two potential regulatory sites, but neither the 5'-flanking region nor the splice sites correlated with variation in OTC activity. In intron 3, two polymorphic sites were found: one comprising a deletion of 401 nucleotides; and the other was a length and sequence polymorphic region located 8 bases upstream from the deletion. The latter polymorphism provides an explanation for phenotypic variation in OTC. Linkage analysis has suggested reassignment of the chicken OTC gene from the suggested Z chromosome to chromosome 1q.

Abstract
Japanese Black fattening steers were used to examine relationships between carcass traits and mitochondria displacement loop (D-loop) variations. The D-loop region of Japanese Black cattle was sequenced and revealed 26 mitochondrial haplotypes defined by 25 polymorphic sites. The haplotypes were classified into five mitochondrial types (type 1 to 5) using the unweighted pair-group method with arithmetic means. Carcass weight, longissimus muscle area (LMA), rib thickness, subcutaneous fat thickness, yield estimate, and beef marbling score (BMS) were compared among five mitochondrial types with BLUP procedures. Significant differences between mitochondria types were detected for LMA and BMS. Difference (P < . 05) was observed between mitochondrial types 2 and 4 for LMA. There was a highly significant difference (P < .01) in BMS between types 2 and 4. Difference (P < .05) was also found between types 1 and 4 on BMS. These results suggest that cytoplasmic genetic effects are important sources of variation for carcass traits in Japanese Black cattle.

Abstract
The cDNAs encoding lactate dehydrogenase isozymes LDH-A (muscle) and LDH-B (heart) from alligator and turtle and LDH-A, LDH-B, and LDH-C (testis) from pigeon were cloned and sequenced. The evolutionary relationships among vertebrate LDH isozymes were analyzed. Contrary to the traditional belief that the turtle lineage branched off before the divergence between the lizard/alligator and bird lineages, the turtle lineage was found to be clustered with either the alligator lineage or the alligator-bird clade, while the lizard lineage was found to have branched off before the divergence between the alligator/turtle and bird lineages. The pigeon testicular LDH-C isozyme was evidently duplicated from LDH-B (heart), so it is not orthologous to the mammalian testicular LDH-C isozymes.

Abstract
The protein-encoding region of L-lactate dehydrogenase (LDH) gene from nematode, Caenorhabditis elegans, was amplified by polymerase-chain-reaction from total genomic DNA and its nucleotide sequence determined. A comparison of this genomic sequence with the published sequence of nematode LDH cDNA reveals the presence of two introns of 57 and 47 nucleotides at codon no. 82 and 279-280, respectively. The positions of the two introns present in this invertebrate LDH gene correspond to the second and sixth introns of vertebrate LDH genes. The protein-coding sequence of human LDH-A (muscle), LDH-B (heart) and LDH-C (testis), mouse LDH-A, and duck LDH-B genes has previously been shown to be interrupted by six introns at the homologous positions.

Abstract
SMXA recombinant inbred (RI) strains of mice were produced by systematic inbreeding from the F2 generation of a cross between two progenitor inbred strains, A/J and SM/J, which differ considerably with respect to many characteristics, and consists of 28 inbred strains. In this study, we investigated the applicability of DNA fingerprinting with M13 phage DNA to the identification of these closely related strains. DNA fingerprints of the SMXA RI strains and their progenitors, SM/J and A/J, showed strain-specific patterns, with the same banding patterns within each strain. Linkage analysis by using strain distribution patterns of minisatellite loci with 108 genetic markers containing microsatellites, biochemical and immunological marker genes allowed 23 minisatellite loci to be assigned to 11 chromosomes. The results suggested that DNA fingerprinting with M13 phage DNA is applicable not only for strain identification but also for genetic monitoring of RI strains on almost all chromosomes.

We used eight C57BL/6 sublines (J parallel Jcl, J parallel Jms, J parallel Slc, J parallel Nrs, J parallel Yok, Jah, N parallel Crj, N parallel Jcl) and eleven C3H/He sublines, (J, J parallel Jcl, J parallel Yok, J parallel Nrs, J parallel Jms, N, N parallel Jcl, N parallel Crj, Slc, Jah, Nrs). Two kinds of restriction endonucleases (HinfI and PstI) were used. It was found that: 1) DNA fingerprint within each subline showed identical patterns. 2) Most sublines of C57BL/6 and C3H/He could be identified using DNA fingerprinting with HinfI except between N parallel Crj and Slc, and among J, J parallel Nrs and J parallel Yok in C3H/He. DNA fingerprints with PstI endonucleases showed low polymorphic banding patterns. 3) A dendrogram constructed from DNA fingerprint patterns reflected generally the genealogy of the sublines used. 4) DNA fingerprinting, therefore, seemed to be suitable for the genetic monitoring and assessment of genetic relationships among sublines of inbred mice having close relationships.

Abstract
It is well known that laboratory rabbits are not controlled genetically like laboratory mice and rats. In order to test the usefulness of DNA fingerprinting in investigation of genetic uniformity of the laboratory rabbits strains and their relationships, we applied DNA fingerprinting using bacteriophage M13 probe to five strains (2 inbreds (JWY-NIBS and DuY-NIBS) and 3 outbreds (JW-NIBS, Icl:JW and WHHL)). DNA fingerprints of 2 inbred strains showed the same banding patterns within each strain but the strain-specific patterns. Although there were no rabbits showing the same banding patterns in 3 outbred strains, average percent differences (APD) were 13.7 to 18.6. A dendrogram based on APD of DNA fingerprints was constructed by 2 large clusters, JW group and DuY. The dendrogram was essentially similar to that based on rabbit mandible measurements. These results suggest that DNA fingerprinting is available not only for the genetic monitoring of the laboratory rabbit strains but also for the investigation of their genetic relationships.

Abstract
Features of a long-haired mutant and inheritance of mutation were investigated in the golden hamster (Mesocricetus auratus). The hair of adult long-haired hamsters was longest at the rump and flanks (approximately 70 mm) and was also unusually long at the neck (45 to 50mm). The hair length of males was more striking than that of females. Mating experiments indicated that an autosomal recessive gene is responsible for the inheritance of long hair. An albino long-haired hamster strain was established by continuous full-sib mating from F2 hybrids, descendants of (acromelanic albino x agouti long-haired) F1 progeny, and genetic homogeneity was confirmed by DNA fingerprinting. The long-haired strain was characterised by the fact that males grew larger than females, in contrast to the other strains of hamsters.
