Inferring the population history of Tai-Kadai-speaking people and southernmost Han Chinese on Hainan Island by genome-wide array genotyping

摘要

Genetic affinity inferred from South-North Cline and East-West Cline based on the first two components (a) and the second and third components (b); c Ancestry proportions of Hlai and Han residing in Hainan Island. Plots representing ancestry components of two studied populations and 67 worldwide present-day populations, showing converged runs of 7 (No substructure emerges in East Asia), 8 (Substructure emerges in East Asia) and 13 (Best predefined k value dissected the genetic structure of our sample set).
