Abstract
- The SNPforID 52-plex single nucleotide polymorphisms (SNPs) were analyzed in four native Venezuelan populations: Bari, Pemon, Panare and Warao. None of the population-locus combinations showed significant departure from Hardy-Weinberg equilibrium. Calculation of forensic and statistical parameters showed lower values of genetic diversity in comparison with African and European populations, as well as other, admixed populations of neighboring regions of Caribbean, Central and South America. Significant levels of divergence were observed between the four Native Venezuelan populations as well as with other previously studied populations. Analysis of the 52-plex SNP loci with Structure provided an optimum number of population clusters of three, corresponding to Africans, Europeans and Native Americans. Analysis of admixed populations indicated a range of membership proportions for ancestral populations consisting of Native American, African and European components. The genetic differences observed in the Native American groups suggested by the 52 SNPs typed in our study are in agreement with current knowledge of the demographic history of the Americas.<br /> (Copyright © 2012 Elsevier Ireland Ltd.
