Figure 1.
Global and regional patterns of population structure. (A) structure analysis with K = 5 for the POPRES populations combined with the HapMap populations. (B–D) For each region, the first two principal components are shown, with the proportion of variance explained by each component shown in parentheses. Results from structure are shown below the PCA results, with K = 2 for East Asia, and K = 3 for South Asia and Mexico. HapMap samples have been included in the East Asia analysis for comparison. In South Asia, individuals have been colored by spoken language group, with each individual's spoken language shown in Supplemental Figure S5.
