Abstract
Latin American countries are distinguished by their highly admixed populations, characterized by a significant preservation of Native American matrilineal ancestry. This contrasts with the paternal lineages, which exhibit different patterns due to pronounced sex-biased mating practices during the colonial period. Uniparental genetic markers have been instrumental in population genetics, facilitating the reconstruction of human settlement histories and serving forensic identification purposes. The primary objective of this study was to investigate the diversity and structure of lineage markers in Argentina and compare them with other admixed populations in South America. For this study, we analyzed Y-STR and mtDNA haplotypes from 5202 unrelated individuals, providing a detailed description of the observed variability in both markers. Additionally, we conducted a genetic distance analysis, incorporating data from bibliographic sources across Argentina and South America. In pairwise comparisons among provinces, higher FST values were found in mtDNA haplotypes than in Y-STR haplotypes. This allows for more provinces to be grouped by similarity when using Y-STR data. These differences were also evident in the multidimensional scaling (MDS) analysis between South American countries. Y-STR haplotypes showed greater similarity to European haplotypes, whereas mtDNA haplotypes exhibited greater dispersion. Thus, the comprehensive compilation of haplotypes in this study, including those integrated from our research and those cited in existing literature, provides an in-depth understanding of the inherent genetic complexities within Argentina.

Unraveling the Genetic Threads of History: mtDNA HVS-I Analysis Reveals the Ancient Past of the Aburra Valley. Genes (Basel) 2023; 14:2036. [PMID: 38002979 PMCID: PMC10670959 DOI: 10.3390/genes14112036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/18/2023] [Accepted: 10/30/2023] [Indexed: 11/26/2023] Open
Abstract
This article presents a comprehensive genetic study focused on pre-Hispanic individuals who inhabited the Aburrá Valley in Antioquia, Colombia, between the tenth and seventeenth centuries AD. Employing a genetic approach, the study analyzed maternal lineages using DNA samples obtained from skeletal remains. The results illuminate a remarkable degree of biological diversity within these populations and provide insights into their genetic connections with other ancient and indigenous groups across the American continent. The findings strongly support the widely accepted hypothesis that the migration of the first American settlers occurred through Beringia, a land bridge connecting Siberia to North America during the last Ice Age. Subsequently, these early settlers journeyed southward, crossing the North American ice cap. Of particular note, the study unveils the presence of ancestral lineages from Asian populations, which played a pivotal role in populating the Americas. The implications of these results extend beyond delineating migratory routes and settlement patterns of ancient populations. They also enrich our understanding of the genetic diversity inherent in indigenous populations of the region. By revealing the genetic heritage of pre-Hispanic individuals from the Aburrá Valley, this study offers valuable insights into the history of human migration and settlement in the Americas. Furthermore, it enhances our comprehension of the intricate genetic tapestry that characterizes indigenous communities in the area.

Abstract
BACKGROUND Argentinean population is the result of admixture between South Amerindians, Europeans and to a lesser degree, Africans. Since the advent of forensic molecular genetics, the construction of local reference databases became mandatory. Aiming to further extend the technical quality reference database of Argentina, we present herein the allele frequencies for 24 autosomal STRs, including D22S1045, and SE33 (not previously reported for Argentina in STRidER). CONCLUSIONS Genotypes of 6454 unrelated individuals (3761 males and 2694 females) from 13 out of 23 provinces were analysed. Forensic parameters were calculated for each marker. The observed heterozygosity ranged from 0.661 (TPOX) to 0.941 (SE33). The locus SE33 was revealed to be the most informative marker showing the highest values for PIC (0.955), GD (0.952), TPI (8.455) and PE (0.879). On the other hand, TPOX turned out to be the least informative marker: PIC (0.618), GD (0.669), and PE (0.371). The high number of analyzed individuals allowed detecting low frequency alleles and microvariants in CSF1PO; D16S539 and D21S11 D18S51; PENTA D; PENTA E and at locus D6S1043. METHODS AND RESULTS This study is the most extensive for Argentina and complements the already reported information concerning the autosomal STRs commonly used in forensic identification. The results were submitted passing STRidER quality control standards (QC), receiving the reference number STR000327 v.2.

Abstract
Immigrants from diverse origins have arrived in Paraguay and produced important demographic changes in a territory initially inhabited by indigenous Guarani. Few studies have been performed to estimate the proportion of Native ancestry that is still preserved in Paraguay and the role of females and males in admixture processes. Therefore, 548 individuals from eastern Paraguay were genotyped for three marker sets: mtDNA, Y-SNPs and autosomal AIM-InDels. A genetic homogeneity was found between departments for each set of markers, supported by the demographic data collected, which showed that only 43% of the individuals have the same birthplace as their parents. The results show a sex-biased intermarriage, with higher maternal than paternal Native American ancestry. Within the native mtDNA lineages in Paraguay (87.2% of the total), most haplogroups have a broad distribution across the subcontinent, and only few are concentrated around the Paraná River basin. The frequency distribution of the European paternal lineages in Paraguay (92.2% of the total) showed a major contribution from the Iberian region. In addition to the remaining legacy of the colonial period, the joint analysis of the different types of markers included in this study revealed the impact of post-war migrations on the current genetic background of Paraguay.

Genetic structure of Mataco-Guaycurú speakers from Argentina and the extent of their genetic admixture with neighbouring urban populations. Sci Rep 2019; 9:17559. [PMID: 31772268 PMCID: PMC6879578 DOI: 10.1038/s41598-019-54146-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Accepted: 11/08/2019] [Indexed: 11/25/2022] Open
Abstract
Argentina hosts more than 30 Native American groups, who are widely distributed throughout the country. Mataco-Guaycurú speakers settled in the ecoregion of Gran Chaco and represent 26.7% of the extant aboriginal population of the country. To further investigate the genetic attributes of these speakers, we focused our attention on four aboriginal groups, namely, Wichí, Toba, Pilagá and Mocoví, belonging to the Mataco-Guaycurú linguistic group. Our main goal was to evaluate the interrelationships among the groups and the relationships of these groups with admixed urban populations and to assess correspondences between molecular analysis and historical information. A total of 890 samples (282 Native Americans and 608 inhabitants of admixed urban areas) were analysed. Genetic information was gathered from 15 autosomal STRs, 17 Y-STRs, entire mtDNA control region sequences, 24 AIM-SNPs and 46 AIM-DIPs. Native American signatures were detected in 97.9% of mtDNA lineages, 89.1% of Y-haplotypes and 90.3% to 96.9% of autosomal markers. Wichí exhibited the genetic composition with the largest Native American contribution among the groups and a weak signal of gene flow. This work provides extended genetic information of potential interest in the fields of molecular anthropology and forensic genetics.
