Fig. 2: Global patterns of genetic differentiation.

A Principal component analysis. A.1 PC1 and PC2; A.2 PC2 and PC3. Each point corresponds to one individual. B Individual ancestry proportions inferred with ADMIXTURE. B.1 K = 2; B.2 K = 3; B.3 K = 4; B.4 K = 5. Each vertical bar corresponds to one individual and the proportion of each colour corresponds to the estimated ancestry proportion from a given cluster. Individuals are grouped from north to south. Sampling locations separated by black lines.
