Cluster analysis and spatial interpolations.
(A and B) TESS bar plots for K = 2-3. Each vertical line represents an individual, and colors represent their inferred ancestry from K ancestral populations. Individuals are ordered by their geographic sampling location. (C and D) Spatial interpolations of the Q matrices generated by the program TESS Ad-Mixer for K = 2-3. Spatial interpolations were plotted on probable extents of chimpanzee ranges in Nigeria and Cameroon.
