P value of Pearson’s correlation coefficient (n = 412).
Q1, Q2, Q3 represent the three sub-populations revealed by GENELAND analysis where pairwise FST were calculated. Q1×Q2 = 0.0118, Q1×Q3 = 0.0226, and Q2×Q3 = 0.02. PC1 represents the first principal component used to correct for population stratification.
