Gene flow from surrounding populations promoted the formation of a subpopulation structure within the HM population. a FST of the pairwise population was the result of randomly selecting 9 samples and repeating it 100 times. Each point represents a repetition. b–d The diamonds denote two target populations, and the other dots denote the populations tested. The Yao samples come from two sites, Guilin and Laibin. The color represents the relative difference in FST between the population to be tested and the two target populations (see “Methods”). The results show that surrounding populations contributed gene flow to the HM populations
