[QUOTE]Originally posted by Clyde Winters: [QB] Everyday more and more evidence supports the African introduction of Y-Chromosome R1 into the Americas. . [QUOTE]Originally posted by xyyman: [qb] -------------------------------- [b]“Distribution of paternal lineages in Mestizo populations throughout Mexico: an in silico study based on Y-STR haplotypes” -J. A. Aguilar-Velázquez[/b] Abstract The Mexican-Mestizo population arose following European contact with the Americas due to[b] the admixture of principally Spaniards, Native Americans, and Africans around 500 years ago.[/b] Because the paternal lineage distribution of the Mexican population has been poorly investigated, this study inferred [b]the haplogroups of ten populations based on 1859 haplotypes (Y-STR data)[/b] using two haplogroup predictor programs. In the Mexican population sample, we found [b]predominantly European ancestry (50.1%), [/b]followed by Native American (32.5%), [b]Eurasian (13.4%),???????[/b] African (2.1%), East African-South Eurasian (1.3%), and Asian (0.6%) ancestries. In general, our results support[b] a contrary north-to-south gradient throughout the Mexican territory of European and Native-American ancestries, respectively[/b]. Moreover, the presence of [b]West-European R1b and Sub-Saharan African E1b1a haplogroups[/b] agrees with historical and genetic data of gene flow during the European conquest. This study represents the effort to analyze these paternal lineages on a large scale by taking advantage of Y-STR haplotype data to determine the distribution and ancestry proportions in this country. Introduction The past 500 years of admixture among[b] Europeans (primarily Spaniards), Native-Americans, and Africans have formed the majority of the contemporary Mestizo (admixed) population from Mexico (~93%).[/b] The National Institute of Anthropology [b]defines a Mestizo as a person born in Mexico who has a Spanish-derived last name and a family with Mexican ancestors who can be traced back to the third generation[/b] [1]. The specific sets of single nucleotide polymorphisms of the Y-chromosome (Y-SNPs) are known as Y-linked haplogroups and constitute paternal lineages related by descent, which enable the definition of the paternal ancestry of individuals and populations. But more astonishing is the E1b1a-V38. These are not West African slaves. Isn’t this Mota? E-V38 is virtually non-existence in West Africa.
