Locations and genetic makeup of the Malays and other populations.
The averaged genetic makeup across individuals of each population are indicated by the bars. Each color represents an independent cluster at K = 9. Southeast Asian 1 and Southeast Asian 2 represent the aboriginal Southeast Asian component and Austronesian component, respectively. All the Malay populations are arranged in the dashed box. Population IDs are shown in Supplementary Table S4. The map is generated using the packages of R v2.11.1, including mapdata v2.2-3, mapplots v1.5 and maps 2.3-9 (http://cran.r-project.org/web/packages/).
