Note: Groups of sites were defined based on maximization of between groups variation. As three alternative configurations occurred for both loci with similar values of F_ct, all three are presented in order of descending F_ct. Columns indicate sources of genetic variation, the amount of variation accounted for by each source expressed as a percentage, and the fixation indices with associated significance levels determined through 1000 permutations of the data.
