Pairwise differences analysis between seven yak populations. About pairwise differences analysis as (1) above diagonal: average number of pairwise differences between populations (πXY); (2) Diagonal elements: average number of pairwise differences within populations (πX); and (3) Below diagonal: corrected average pairwise differences (πXY-(πX+πY).
