A Locations of East African populations sampled in this study across Ethiopia and Tanzania. B Principal component analysis of genetic data across 162 East Africans, combined with 20 West African Yoruba (YRI), 20 European Americans (CEU), and 20 Han Chinese (CHB) from the 1000 Genomes Project. The percent variance explained by each principal component is indicated in parentheses. C ADMIXTURE analysis of East African, YRI, CEU, and CHB populationsBack to article page
