(a) PCA of chimpanzee individuals from the species distribution range in Africa and zoo specimens of unknown origin. Colours: yellow, pink, turquoise and green for P. t. verus, P. t. troglodytes, P. t. schweinfurthii and zoo specimens, respectively. The pink dot falling within the outer range of the P. t. schweinfurthii cluster represents the, based on the STRUCTURE analysis, misclassified individual Choupette. In (b), three simulated F1 hybrid populations are included, each consisting of 20 individuals. The populations are colour coded light grey, medium grey and dark grey for P. t. troglodytes/P. t. schweinfurthii, P. t. schweinfurthii/P. t. verus and P. t. verus/P. t. troglodytes, respectively.
