For the correct evaluation of the weight of genetic evidence in a forensic context, databases must reflect the structure of the population, with all possible groups being represented. Countries with a recent history of admixture between strongly differentiated populations are usually highly heterogeneous and sub-structured. Bolivia is one of these countries, with a high diversity of ethnic groups and different levels of admixture (among Native Americans, Europeans and Africans) across the… 

The Ancestry of Eastern Paraguay: A Typical South American Profile with a Unique Pattern of Admixture

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 and showed a sex-biased intermarriage, with higher maternal than paternal Native American ancestry.

Demand for larger Y-STR reference databases in ethnic melting-pot countries: Argentina as a test case

This work proposes organizing Y-STR haplotype reference databases according to the most frequent haplogroups detected in a given admixed population, probably due to the different proportions of the Native American Q3-M3 haplogroup in the studied samples.

Population data of 15 autosomal STR markers from Afro-Bolivians of Nor Yungas Province (Bolivia)

The multidimensional scaling (MDS) plot supported that Afro-Bolivians of Nor Yungas preserved a stronger African descent compared to other admixed Latin American populations and amplified the Bolivian databases of autosomal STR loci.

Genetic diversity and phylogeographic analysis of human herpesvirus type 8 (HHV-8) in two distant regions of Argentina: association with the genetic ancestry of the population

Evidence of the geographic circulation of HHV-8 in Argentina is given and new insights about its relationship with ancient and modern human migrations are provided to identify the possible origins of this virus in Argentina.

Continental Origin for Q Haplogroup Patrilineages in Argentina and Paraguay

The aim of present work was to identify the continental origin of the remaining Q lineages, and analyzed the STR haplotypes for the samples and compared them with haplotypes described by other authors for the rest of the world.

Ancestral genetic legacy of the extant population of Argentina as predicted by autosomal and X-chromosomal DIPs.

This work shows the ability of the tested DIP panels to infer ancestry and confirm mating bias, and the observed differences between the estimated continental genetic contribution proportions based on autosomal DIPs and X-DIPs reflect the effects of autosome andX-chromosome transmission behaviour and their different recombination patterns.

Outlining the Ancestry Landscape of Colombian Admixed Populations

Investigating and comparing patterns of genetic ancestry in Colombia by studying samples from Native and non-Native populations living in its 5 continental regions found significant differences were observed between Native andNon- Native populations, among non-native populations from different regions and among Native populations fromDifferent ethnic groups.

Genetic admixture patterns in Argentinian Patagonia

The results showed that differences on continental ancestry contribution have different origins in each region in Patagonia, and even in each locality, highlighting the importance of knowing the origin of the participants and their ancestors for the correct interpretation and contextualization of the genetic information.



Y-chromosome analysis reveals genetic divergence and new founding native lineages in Athapaskan- and Eskimoan-speaking populations

The data suggest that Canadian Eskimoan- and Athapaskan-speaking populations are genetically distinct from one another and that the formation of these groups was the result of two population expansions that occurred after the initial movement of people into the Americas.

Major Mitochondrial DNA Haplotype Heterogeneity in Highland and Lowland Amerindian Populations from Bolivia

Frequency analyses under geographic, historic, linguistic, and genetic configurations using the statistic of Weir (Weir 1990) and analysis of molecular variance (AMOVA) show similar results.

Comparison of the genetic background of different Colombian populations using the SNPforID 52plex identification panel

From the observed genetic backgrounds, it is possible to conclude that a single reference database for the entire country would not be suitable for forensic purposes.

Colombia’s racial crucible: Y chromosome evidence from six admixed communities in the Department of Bolivar

Heterogeneous patterns of admixture reveal a genetic substructure within the Department of Bolivar, where five out of the six communities studied exhibit a predominantly European gene pool.

Genetic analysis of ancestry, admixture and selection in Bolivian and Totonac populations of the New World

The authors identify highly-divergent New World SNPs that coincide with high-frequency haplotypes found at similar frequencies in all populations examined, including the HGDP Pima, Maya, Colombian, Karitiana, and Surui American populations.

Digging deeper into East African human Y chromosome lineages

The detection of a new haplogroup B2a1b defined by G1, could be, therefore, important to differentiate Nilotes from other groups, helping to trace migration and admixture events that occurred in eastern Africa.

Male lineages in South American native groups: evidence of M19 traveling south.

A heterogeneous contribution of Europeans to these populations is illustrated and supports previous studies showing that most Native American groups were subjected to European admixture that primarily involved immigrant men.

Microsatellites provide evidence for Y chromosome diversity among the founders of the New World.

The hypothesis of a single-founder Y haplotype for Amerinds is evaluated by using 11 Y-specific markers in five Colombian Amerind populations to demonstrate the existence of at least two Amerind founder haplotypes, one of them largely restricted to Native Americans.

mtDNA and Y-chromosome diversity in Aymaras and Quechuas from Bolivia: different stories and special genetic traits of the Andean Altiplano populations.

Particular genetic characteristics presented by both samples support a past common origin of the Altiplano populations in the ancient Aymara territory, with independent, although related histories, with Peruvian (Quechuas) populations.

A major Y-chromosome haplogroup R1b Holocene era founder effect in Central and Western Europe

Within the M412 dichotomy, the major S116 sub-clade shows a frequency peak in the upper Danube basin and Paris area with declining frequency toward Italy, Iberia, Southern France and British Isles, and more complex pre-Neolithic scenarios remain possible for the L23(xM412) components in Southeast Europe and elsewhere.
