Below the diagonal: Pairwise-Fst were calculated following the Weir and Cockerham (1984) indications. ^∗indicates significant Fst (p < 0.001) after 1,000 permutations. Above the diagonal: Exact p-values of the exact test of sample differentiation based on haplotype frequencies with Markov chain length of 10,000 steps (Raymond and Rousset, 1995; Goudet et al., 1996).
