Culturally defined regions of historical Tibet and geographical locations of Sherpa and Tibetan samples analyzed in this study. The culturally defined regions in historical Tibet are illustrated in different colors: red, Ü-Tsang (central Tibet); green, Kham (eastern Tibet); and purple, Amdo (northeastern Tibet). Dots with distinct colors represent subgroups classified according to the collected geographical locations: blue for two SHP subpopulations; and non-blue for regional Tibetans. The locations of Amdo and Kham regions make Tibetans there more easily influenced by cultures and genetics from East Asians or Central Asians/Siberians. The figure was modified from one obtained from Wikipedia (https://en.wikipedia.org/wiki/Kham)
