Graphical display of estimated population structure at K = 4. Each vertical line represents one individual. At K = 4, the samples are partitioned into four populations, which are consistent with large geographical regions of Melanesia, East Asia, Southeast Asia and the rest of the world. Populations are separated by black lines and occurred in the same order as given in Table 2.
