Two-dimension maps obtained by spatial interpolation of the ancestral contribution coefficients (Q values) for genetic clusters I, II and III obtained with STRUCTURE for K = 3. Each sampled breed is represented by a black dot placed at the center of its geographical dispersion (see Fig. 1 for breed names). Colors in the maps indicate the degree of genetic similarity among the breeds sampled, such that breeds sharing a lighter color (decreasing from white to pink and then to orange) have a higher contribution of the indicated cluster, while breeds with a darker color (dark green) do not share a contribution from that cluster
