The Ami and Yami aborigines of Taiwan and their genetic relationship to East Asian and Pacific populations.

ABSTRACT: This article reports on the genetic characteristics of the Ami and Yami, two aboriginal populations of Taiwan. Y-SNP and mtDNA markers as well as autosomal SNPs were utilized to investigate the phylogenetic relationships to groups from MSEA (mainland Southeast Asia), ISEA (island Southeast Asia), and Oceania. Both the Ami and Yami have limited genetic diversity, with the Yami having even less diversity than the Ami. The partitioning of populations within the PCA plots based on autosomal SNPs, the profile constitution observed in the structure analyses demonstrating similar composition among specific populations, the average IBD (identical by descent) tract length gradients, the average total length of genome share among the populations, and the outgroup f3 results all indicate genetic affi
