Notes: Above diagonal: pairwise F_ST values between populations. Diagonal elements: average number of pairwise differences within populations (PiX). Below diagonal: corrected average pairwise difference (PiXY-(PiX+PiY)/2). Pairwise F_ST values that are statistically different are indicated (P < 0.01).
