Figure 3. Plots of population diversity against geographic distance to East Africa (Addis Ababa).

A: Vp against geographic distance for the Frequency dataset; B: He against geographic distance for the Frequency dataset; C: Vp against geographic distance for the Genotype dataset; D: He against geographic distance for the Genotype dataset. The determination coefficient (R²) estimates the proportion of the variation in genetic diversity that is explained by the variation in geographic distance to East Africa.
