Number of population samples in contrast is given in parentheses. “African regions” denotes the West, East, and South African groups; “all regions” denotes the three African groups and the non-African sample. Only B alleles were included (see the “Results” section).

Hudson's (2000) S_nn statistic. Significance was assessed by permutation tests (P<.001 [in boldface italics]; see the “Subjects and Methods” section).
