Regional genetic structure of indigenous pig populations in Asia and Europe. a, d show the results of the MDS analysis of pig populations from Asia (40 breeds) and Europe (26 breeds). Each point represents a breed, colors are assigned to each breed according to their geographical distributions, which are visualized in (b) and (e) for Asian and European pigs, respectively. c, f show the correlation between genetic and geographic distances among pig breeds in Asia and Europe, respectively. The legends of pig breeds are shown on the right. The upper legends in the blue box are for Asian breeds and the legends below in red box are for European breeds
