$F_{\mathrm{ST}}$ values for sets of geographic regions as a function of K, the number of regions considered. (A) ${\overline{F}}_{\mathrm{ST}}$ computed using Equation 10. (B) ${\overline{F}}_{\mathrm{ST}}/{\overline{F}}_{\max }$ computed using Equation 11. For each subset of populations, the value of $F_{\mathrm{ST}}$ is taken from Figure 5. The mean across subsets for a fixed K appears as a solid red line, and the median as a dashed red line.
