Figure 3.

Plot over pairwise F_ST across populations for microsatellites, SNPs, and MHC. Each value is a data point for pairwise F_ST between two populations. All pairs are represented by open circles. Small circles are pairwise F_ST were at least one of the two populations is a small isolated population. The larger circles in a lane on the right side of the small circles are all other population pairs, including both isolated and continuous population pairs. The negative F_ST values (below the dotted line) should be interpreted as no differentiation between pairs.
