Hardy-Weinberg Equilibrium Test for GM6 genotypes.

Chi-square tests were used to determine deviation from HWE, and F(is) was calculated based on the formula F = 1– Het/HetHW, where Het is the number of heterozygotes observed, and HetHW is the number of heterozygotes expected under HWE [33], [34].采用卡方检验（Chi-square tests）检测群体是否偏离哈迪-温伯格平衡（Hardy-Weinberg Equilibrium，HWE），并基于公式$F = 1 – ext{Het}/ ext{HetHW}$计算F(is)，其中Het为观测杂合子数，HetHW为哈迪-温伯格平衡下的预期杂合子数[33, 34]。
