Abstract
The main goal of this study was to develop a comparative multi-colour Zoo-FISH on domestic ruminants metaphases using a combination of whole chromosome and sub-chromosomal painting probes obtained from the river buffalo species (Bubalus bubalis, 2n = 50,XY). A total of 13 DNA probes were obtained through chromosome microdissection and DOP-PCR amplification, labelled with two fluorochromes and sequentially hybridized on river buffalo, cattle (Bos taurus, 2n = 60,XY), sheep (Ovis aries, 2n = 54,XY) and goat (Capra hircus, 2n = 60,XY) metaphases. The same set of paintings were then hybridized on bovine secondary oocytes to test their potential use for aneuploidy detection during in vitro maturation. FISH showed excellent specificity on metaphases and interphase nuclei of all the investigated species. Eight pairs of chromosomes were simultaneously identified in buffalo, whereas the same set of probes covered 13 out 30 chromosome pairs in the bovine and goat karyotypes and 40% of the sheep karyotype (11 out of 27 chromosome pairs). This result allowed development of the first comparative M-FISH karyotype within the domestic ruminants. The molecular resolution of complex karyotypes by FISH is particularly useful for the small chromosomes, whose similarity in the banding patterns makes their identification very difficult. The M-FISH karyotype also represents a practical tool for structural and numerical chromosome abnormalities diagnosis. In this regard, the successful hybridization on bovine secondary oocytes confirmed the potential use of this set of probes for the simultaneous identification on the same germ cell of 12 chromosome aneuploidies. This is a fundamental result for monitoring the reproductive health of the domestic animals in relation to management errors and/or environmental hazards.

Abstract
Evaluating homology between the sex chromosomes of different species is an important first step in deducing the origins and evolution of sex-determining mechanisms in a clade. Here, we describe the preparation of Z and W chromosome paints via chromosome microdissection from the Australian marbled gecko (Christinus marmoratus) and their subsequent use in evaluating sex chromosome homology with the ZW chromosomes of the Kwangsi gecko (Gekko hokouensis) from eastern Asia. We show that the ZW sex chromosomes of C. marmoratus and G. hokouensis are not homologous and represent independent origins of female heterogamety within the Gekkonidae. We also show that the C. marmoratus Z and W chromosomes are genetically similar to each other as revealed by C-banding, comparative genomic hybridization, and the reciprocal painting of Z and W chromosome probes. This implies that sex chromosomes in C. marmoratus are at an early stage of differentiation, suggesting a recent origin.

Abstract
The catarrhine primates were the first group of species studied with comparative molecular cytogenetics. Many of the fundamental techniques and principles of analysis were initially applied to comparisons in these primates, including interspecific chromosome painting, reciprocal chromosome painting and the extensive use of cloned DNA probes for evolutionary analysis. The definition and importance of chromosome syntenies and associations for a correct cladistics analysis of phylogenomic relationships were first applied to catarrhines. These early chromosome painting studies vividly illustrated a striking conservation of the genome between humans and macaques. Contemporarily, it also revealed profound differences between humans and gibbons, a group of species more closely related to humans, making it clear that chromosome evolution did not follow a molecular clock. Chromosome painting has now been applied to more that 60 primate species and the translocation history has been mapped onto the major taxonomic divisions in the tree of primate evolution. In situ hybridization of cloned DNA probes, primarily BAC-FISH, also made it possible to more precisely map breakpoints with spanning and flanking BACs. These studies established marker order and disclosed intrachromosomal rearrangements. When applied comparatively to a range of primate species, they led to the discovery of evolutionary new centromeres as an important new category of chromosome evolution. BAC-FISH studies are intimately connected to genome sequencing, and probes can usually be assigned to a precise location in the genome assembly. This connection ties molecular cytogenetics securely to genome sequencing, assuring that molecular cytogenetics will continue to have a productive future in the multidisciplinary science of phylogenomics.

Abstract
We report on reciprocal painting between humans and two Cercopithecini species, Erythrocebus patas (patas monkey) and Cercopithecus neglectus (De Brazza's monkey). Both human and monkeys chromosome-specific probes were made by degenerate oligonucleotide primed PCR (DOP-PCR) from flow sorted chromosomes. Metaphases of both monkey species were first hybridized with human chromosome-specific probes and then human metaphases were hybridized with chromosome paints from each monkey species. The human paint probes detected 34 homologous segments on the C. neglectus karyotype, while the C. neglectus probes, including the Y, revealed 41 homologous segments on the human karyotype. The probes specific for human chromosomes detected 29 homologous segments in the E. patas karyotype, while the patas monkey probes painted 34 segments on the human karyotype. We tested various hypotheses of Cercopithecini phylogeny and taxonomy developed by morphologists, molecular biologists and cytogeneticists. Our hybridization data confirm that fissions (both Robertsonian and non-Robertsonian) are the main mechanism driving the evolutionary trend in Cercopithecini toward higher diploid numbers and strongly suggest an early phylogenetic bifurcation in Cercopithecini. One branch leads to Cercopithecus neglectus/Cercopithecus wolfi while the other line leads to Erythrocebus patas/Chlorocebus aethiops. Allenopithecus nigroviridis may have diverged prior to this major phylogenetic node.

Abstract
The exceptional diploid number (2n=48) of the proboscis monkey (Nasalis larvatus) has played a pivotal role in phylogenies that view the proboscis monkey as the most primitive colobine, and a long-isolated genus of the group. In this report we used molecular cytogenetic methods to map the chromosomal homology of the proboscis monkey in order to test these hypotheses. Our results reveal that the N. larvatus karyotype is derived and is not primitive in respect to other colobines (2n=44) and most other Old World monkeys. The diploid number of 2n=48 can be best explained by derived fissions of a segment of human chromosomes 14 and 6. The fragmentation and association of human chromosomes 1 and 19 as seen in other Asian colobines, but not in African colobines, is best explained as a derived reciprocal translocation linking all Asian colobines. The alternating hybridization pattern between four segments homologous to human chromosomes 1 and 19 on N. larvatus chromosome 6 is the result of the reciprocal translocation followed by a pericentric inversion. N. larvatus shares this pericentric inversion with Trachypithecus, but not with Pygathrix. This inversion apparently links Nasalis and Trachypithecus after the divergence of Pygathrix. The karyological data support the view that Asian colobines, including N. larvatus, are monophyletic. They share many linking karyological features separating them from the African colobines. The hybridization pattern also suggests that Nasalis is nested within Asian Colobines and shares a period of common descent with other Asian colobines after the divergence of Pygathrix.

Abstract
An unexpected finding of the human genome was the large fraction of the genome organized as blocks of interspersed duplicated sequence. We provide a comparative and phylogenetic analysis of a highly duplicated region of 16p12.2, which is composed of at least four different segmental duplications spanning in excess of 160 kb. We contrast the dispersal of two different segmental duplications (LCR16a and LCR16u). LCR16a, a 20 kb low-copy repeat sequence A from chromosome 16, was shown previously to contain a rapidly evolving novel hominoid gene family (morpheus) that had expanded within the last 10 million years of great ape/human evolution. We compare the dispersal of this genomic segment with a second adjacent duplication called LCR16u. The duplication contains a second putative gene family (KIAA0220/SMG1) that is represented approximately eight times within the human genome. A high degree of sequence identity (approximately 98%) was observed among the various copies of LCR16u. Comparative analyses with Old World monkey species show that LCR16a and LCR16u originated from two distinct ancestral loci. Within the human genome, at least 70% of the LCR16u copies were duplicated in concert with the LCR16a duplication. In contrast, only 30% of the chimpanzee loci show an association between LCR16a and LCR16u duplications. The data suggest that the two copies of genomic sequence were brought together during the chimpanzee/human divergence and were subsequently duplicated as a larger cassette specifically within the human lineage. The evolutionary history of these two chromosome-specific duplications supports a model of rapid expansion and evolutionary turnover among the genomes of man and the great apes.

Abstract
We used in situ hybridization of chromosome specific DNA probes ("chromosome painting") of all human chromosomes to establish homologies between the human and the white and black colobus (Colobus guereza 2n = 44). The 24 human paints gave 31 signals on the autosomes (haploid male chromosomes homologus to human 14 and 15, 21 and 22, form colobine chromosomes 6 and 16, respectively. Reciprocal translocations were found between human chromosomes 1 and 10, 1 and 17, as well as 3 and 19. The alternating hybridization signals between human 3 and 19 on Colobus chromosome 12 show that in this case a reciprocal translocation was followed by a pericentric inversion. The hybridization data show that in spite of the same diploid number and similar Fundamental Numbers, the black and white colobine monkey differs from Presbytis cristata, an Asian colobine, by 6 reciprocal translocations. Comparisons with the hybridization patterns in other primates show that some Asian colobines have a more derived karyotype with respect to African colobines, macaques, great apes, and humans. Chromosome painting also clearly shows that similarities in diploid number and chromosome morphology both between colobines and gibbons are due to convergence.

Abstract
Marsupial karyotypes have shown extensive conservation even between distantly related groups with a high diversity of life forms and reproductive biology. Banding analysis has been the main test for assessing their homologies and chromosome rearrangements. More recently, cross-species reciprocal chromosome painting has been developed and applied to several mammalian species and has shown homologies and rearrangements not revealed by banding analysis. Karyotype relationships between four marsupial species, Sminthopsis crassicaudata, Potorous tridactylus, Trichosurus vulpecula and Macropus eugenii, which are from different families in two orders, were investigated and presented in the form of comparative chromosome maps. These show that only a limited number of chromosomal rearrangements have occurred during their evolution. A karyotype phylogeny of the four marsupials was derived from these maps. A comparison between published gene location and the comparative chromosome maps for these species is presented and inconsistencies with previous gene mapping data indicated.

Abstract
Chromosomal homologies were established between human and two Chinese langurs (Semnopithecus francoisi, 2n = 44, and S. phayrei, 2n = 44) by chromosome painting with chromosome-specific DNA probes of all human chromosomes except the Y. Both langur species showed identical hybridization patterns in addition to similar G-banding patterns. In total, 23 human chromosome-specific probes detected 30 homologous chromosome segments in a haploid langur genome. Except for human chromosomes 1, 2, 6, 16 and 19 probes, which each gave signals on two non-homologous langur chromosomes respectively, all other probes each hybridized to a single chromosome. The results indicate a high degree of conservation of chromosomal synteny between human and these two Chinese langurs. The human chromosome 2 probe painted the entire euchromatic regions of langur chromosomes 14 and 19. Human chromosome 1 probe hybridized to three regions on langur autosomes, one region on langur chromosome 4 and two regions on langur chromosome 5. Human 19 probe hybridized on the same pattern to one region on chromosome 4 and to two regions on langur chromosome 5, where it alternated with the human chromosome 1 probe. Human 6 and 16 probes both hybridized to one region on each of the two langur autosomes 15 and 18. Only two langur chromosomes (12 and 21) were each labelled by probes specific for two whole human chromosomes (14 and 15 and 21 and 22 respectively). Comparison of the hybridization patterns of human painting probes on these two langurs with the data on other Old World primates suggests that reciprocal and Robertsonian translocations as will as inversions could have occurred since the divergence of human and the langurs from a common ancestor. This comparison also indicates that Asian colobines are karyotypically more closely related to each other that to African colobines.

Abstract
Great apes (Pongidae) possess a chromosome similar to human chromosome 21 (HSA21), whose trisomy was described in both chimpanzee and orangutan. Having studied more than 200 mammalian species by chromosome banding techniques and reconstructed Primates phylogeny, we reinvestigated, using fluorescence in situ hybridization, primate and non-primate mammals that we considered to possess a karyotype representative of their taxonomic group. DNA sequences from HSA21 and human chromosome 3 (HSA3) are synthenic and form a large and similar chromosome in species from distinct orders, such as Primates, Carnivora, Artiodactyla and Scandentia. In Primates, this syntheny was maintained in lemurs and was disrupted by a fission in Old World monkeys (catarrhines). Another fission occurred in New World monkeys (platyrrhines), conserving a syntheny between HSA21 and a very short segment of HSA3 DNA sequences. Thus, the ancestral HSA21 was formed after the divergence between platyrrhines and catarrhines and before the emergence of Cercopithecidae. This exposed the human and Pongidae ancestry to trisomy 21 for a period of 30-50 million years, while, in other catarrhines, the equivalent of HSA21 was further involved in various translocations forming large chromosomes whose aneuploidy, very probably incompatible with life, protected them against trisomy 21.

Abstract
Most primates studied have the usual XX/XY sex-chromosome system. However, exceptions to this rule among howler monkeys have been suggested by several authors. Recently a quadrivalent was discovered in male meiosis of Alouatta caraya and it was established that this species has an X1X2Y1Y2 sex chromosome system. On that basis, a cytogenetic analysis of 25 males of this species is described, showing the corrected karyotype of this species. Each chromosome involved in the particular sex-chromosome system of this species is identified on the basis of mitotic chromosome measurements, G and C-banding patterns as well as on the relative measurements of synaptonemal complexes. It is now established that A. caraya has a karyotype with 2n = 52 in both sexes, and that the male one shows a single autosome #7 (X2) besides the X (X1) and the two products of the reciprocal translocation between the second autosome #7 and the Y chromosome (Y1 and Y2), while females show a homomorphic pair #7 (X2) and a pair of X1. The evolutionary implications of the exceptional primate species having composite sex-chromosome systems are discussed.

Abstract
Mouse and rat genome studies are vital to the use of rodents as models of biology and human genetic disease. In this study, comparative cytogenetic maps of individual homologous mouse (Mus musculus) and rat (Rattus norvegicus) chromosomal regions are presented as defined by cross-species fluorescence in situ hybridization. Such "Zoo-FISH" methods permit direct visual observation of the location of DNA segments from one species on mitotic chromosomes of evolutionarily diverged species. Mouse whole chromosome paint (WCP) probes generated from microdissection and degenerate oliogonucleotide primed (DOP) PCR were hybridized on slides containing a mixture of both mouse (the reference species) and rat (the diverged/ comparative species) metaphase chromosomes. Using six different mouse WCPs, eight regions on seven rat chromosomes were shown to be evolutionarily conserved between these species. The specific chromosomal sites of homology delineated in this study between mouse (MMU) and rat (RNO) genomes include the following: MMU 1 to RNO 9q21-q36 and to RNO 13 from bands q11 to the telomere, MMU 4 to all of RNO 5, MMU 11 to all of RNO 10 and the distal region of RNO 14 (14q21-q22), MMU 7 and MMU 19 both to RNO 1, from bands 1q21 to 41 (MMU 7) and 1q42 to the telomere (MMU 19), and MMU X to all of RNO X. Additionally, several new mouse and rat map assignments have been predicted based on the observed cross-species hybridization patterns in conjunction with known mapping data for mouse or rat genes.

Abstract
We hybridized human chromosome-specific DNA probes to metaphases of the New World monkey Ateles geoffroyi to map the chromosomal homology between these two species. In the haploid Ateles geoffroyi karyotype the total number of signals was 51 for the 22 human autosomal probes used. Compared with Old World monkeys, the number of translocations found in the black-handed spider monkey karyotype was quite striking. The majority of these translocations are apparently Robertsonian and no reciprocal translocations were revealed. Nine autosomal human chromosome probes (11, 13, 14, 17, 18, 19, 20, 21, 22) provided only two signals each per metaphase, but six of these were translocated to subregions of different spider monkey chromosomes. The other 13 autosomal human chromosome paints (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 16) provided fragmented signals. Three human probes (5, 8, 10) provided signals located on two pairs of spider monkey chromosomes. Four human paints (2, 3, 4, 12) provided hybridization signals on three pairs of chromosomes. Probes 6, 7, 15 provided six signals each on two pairs of chromosomes; probe 16 gave eight signals on two pairs of spider monkey chromosomes and probe 1 gave 12 signals on four pairs of chromosomes. The synteny between segments to human 18/8 appears to be an apomorphic ancestral condition for all New World monkeys. A synteny between regions homologous to human 16/10, 5/7 and 2/16 HSA is probably an apomorphic ancestral condition for all Cebidae. The syntenic association 3/15 and 4/1 is an apomorphic condition for the Atelinae.

Abstract
We employed in situ hybridization of chromosome-specific DNA probes ("chromosome painting") of all human chromosomes to establish homologies between the human and the silvered lead monkey karyotypes (Presbytis cristata 2n = 44). The 24 human paints gave 30 signals on the haploid female chromosome set and 34 signals on the haploid male chromosome set. This difference is due to a reciprocal translocation between the Y and an autosome homologous to human chromosome 5. This Y/autosome reciprocal translocation which is unique among catarrhine primates has produced a X1X2Y1Y2/X1X1X2X2 sex-chromosome system. Although most human syntenic groups have been maintained in the silvered leaf monkey chromosomes homologous to human chromosomes 14 and 15, 21 and 22 have experienced Robertsonian fusions. Further, the multiple FISH signals provided by libraries to human chromosomes 1/9, 6/16 indicate that these chromosomes have been split be reciprocal translocations. G-binding analysis shows three different forms of chromosome 1 (X2) which differ by a complex series of inversions in the 10 individuals karyotype. Comparisons with the hybridization patterns in hylobatids (gibbons and siamang) demonstrate that resemblances in chromosomal morphology and banding previously taken to indicate a special phylogenetic relationship between gibbons and colobines are due to convergence.

Abstract
We hybridized whole human chromosome-specific DNA libraries to chromosomes of two supposed subspecies of Alouatta seniculus: Alouatta seniculus sara and Alouatta seniculus arctoides. The number of hybridization signals per haploid set is 42 in A. s. sara and 43 in A. s. arctoidea; the two karyotypes differ by at least 16 chromosomal rearrangements, including numerous translocations. An unusual sex chromosome system is shared by both taxa. The sex chromosome system results from a Y translocation with a chromosome homologous to parts of human chromosome 3/15 and can be described as X1X2Y1Y2/X1X1X2X2 (male/female). Both red howlers also have microchromosomes, a highly unusual karyological trait not found in other higher primates. These microchromosomes are not hybridized by any human chromosome paint and therefore are probably composed of repetitive DNA. It is well known that New World monkeys have high karyological variability. It is probable that molecular cytogenetic analyses including chromosome painting will permit an accurate reconstruction of the phylogeny of these monkeys and help establish the ancestral karyotype for higher primates.

Abstract
Human chromosome specific libraries (CSLs) were individually applied to equine metaphase chromosomes using the fluorescence in situ hybridization (FISH) technique. All CSLs, except Y, showed painting signals on one or several horse chromosomes. In total 43 conserved chromosomal segments were painted. Homoeology could not, however, be detected for some segments of the equine genome. This is most likely related to the very weak signals displayed by some libraries, rather than to the absence of similarity with the human genome. In spite of divergence from the human genome, dated 70-80 million years ago, a fairly high degree of synteny conservation was observed. In seven cases, whole chromosome synteny was detected between the two species. The comparative painting results agreed completely with the limited gene mapping data available in horses, and also enabled us provisionally to assign one linkage group (U2) and one syntenic group (NP, MPI, IDH2) to specific equine chromosomes. Chromosomal assignments of three other syntenic groups are also proposed. The findings of this study will be of significant use in the expansion of the hitherto poorly developed equine gene map.

Abstract
We have used Alu polymerase chain reaction generated probes from rearranged human/rodent somatic cell hybrids for fluorescence in situ hybridization and comparative mapping of some intrachromosomal changes in the karyotypes of great apes (Pan troglodytes, P. paniscus, Gorilla gorilla, Pongo pygmaeus), a gibbon (Hylobates lar), and an Old World monkey (Macaca fuscata). Probes containing chromosomes 2 and 18 fragments confirmed inversions already suggested by the banding pattern of great ape homologues. However, a chromosome 3 fragment showed complex rearrangements in the gibbon and macaque karyotype which were previously not well defined from banding. 'Subchromosomal painting' will allow the identification of intrachromosomal changes on the basis of DNA homology and provides a powerful method to study karyological and genomic evolution.

Abstract
Fluorescence in situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will help to clarify phylogenetic relationships. We used a DNA library established by microdissection and microcloning from the entire long arm of human chromosome 2 for fluorescence in situ hybridization and comparative mapping of the chromosomes of human, great apes (Pan troglodytes, Pan paniscus, Gorilla gorilla, Pongo pygmaeus) and Old World monkeys (Macaca fuscata and Cercopithecus aethiops). Inversions were found in the pericentric region of the primate chromosome 2p homologs in great apes, and the hybridization pattern demonstrates the known phylogenetically derived telomere fusion in the line that leads to human chromosome 2. The hybridization of the 2q microlibrary to chromosomes of Old World monkeys gave a different pattern from that in the gorilla and the orang-utan, but a pattern similar to that of chimpanzees. This suggests convergence of chromosomal rearrangements in different phylogenetic lines.
