Ancestry dynamics in a South American population: The impact of gene flow and preferential mating

In a population from Antioquia, Colombia with an estimated 79% European autosomal ancestry and an estimated 69% European X-chromosome ancestry, about 15% male gene flow from Europe or about 20% mating or reproductive advantage of Europeans over Amerindians...

Outlining the Ancestry Landscape of Colombian Admixed Populations

We sought to investigate and compare patterns of genetic ancestry in Colombia by studying samples from Native and non-Native populations living in its 5 continental regions: the Andes, Caribe, Amazonia, OrinoquĂ­a, and Pacific regions. For this purpose, 46 AIM-Indels were genotyped in 761 non-related individuals from current populations.

A2

Haplogroup A2 is an Native Americas branch on the maternal tree of human kind. The woman who founded this line lived between 13,900 and 17,400 years ago (Behar et al 2012b).

A2a4

Haplogroup A2a4 is a Native Americas branch on the maternal tree of humanity. It is a young branch on the tree, and the woman who founded it lived in a Native North American population between very recent generations and 800 years ago. (Achilli et al., 2013)

Y chromosome STR haplotypes in the Caribbean city of Cartagena (Colombia)

Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena.

Y-chromosome STRs in an Antioquian (Colombia) population sample

Haplotype data were obtained from a sample of 777 unrelated male individuals from Antioquia Department (Colombia), for eight Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393). A total of 442 different haplotypes were identified of which 334 were represented only once in the database and the most frequent haplotype was found in 32 individuals...
