Fig. 2. Shared alleles between Hlai, and Han and other references inferred from three or four-population tests.
a,b Outgroup f3-statistics (three-population tests) in the form f3 (X, Haikou Han; Yoruba) or (X, Qiongzhong Hlai; Yoruba), where X is a reference population from Dataset1. A higher value (red) denotes higher shared genetic drift between our studied populations and the included present-day reference populations. c–e D-statistics in the form of D(studied populations, Dai/Haikou Han/Beijing Han; X, Yoruba) shows the shared branch length between two investigated populations or Dai/Haikou Han/Beijing Han and all worldwide tested populations. Negative D values with significant Z-scores indicate that the included reference population shares more derived alleles with Dai/Haikou Han/Beijing Han populations than with others, and positive D values with significant Z-scores indicate that the tested population shares more alleles with studied populations than with others. The absolute value of Z-score larger than 3 is considered as statistically significant.
