This study investigated the genetic diversity of all nine major Taiwanese aboriginal tribes: Ami, Atayal, Bunun, Ruka, Paiwan, Saisat, Puyuma, Tsou, and Yami
The study determined that these nine major aboriginal populations have limited intra-genetic diversity and are highly heterogeneous from each other, possibly due to endogamy, isolation, drift, and/or unique ancestral populations. The phylogenetic analyses performed indicate that the genetic diversity among all nine tribes is greater than the diversity observed among the worldwide reference populations examined, indicating an extreme case of genetic heterogeneity among these tribes that have lived as close neighbors for thousands of years confined to the limited geographic area of an island. Regarding the tools of the study, compared to the 17 Yfiler marker system, the six additional loci in the new PowerPlex Y23 system provides greater improvement of forensic parameter values in populations with limited genetic heterozygosity. 3 tables, 2 figures, and 22 references
