Table 4.

Pairwise population differentiation based on allelic frequencies of 14 polymorphic microsatellites estimated as Jost D values (below the diagonal) and Slatkin linearized F_ST values (above the diagonal) for each of the eight (top) and two (bottom) values used in microsatellite population scenarios. All comparisons were statistically significant (P < 0.005) based on 10,000 permutations.
