Supplementary Figure 1: Principal-components analyses.
From: A thrifty variant in CREBRF strongly influences body mass index in Samoans
(a) Scatterplot of the first three principal components from the principal-components analysis of the Samoan and HapMap phase 3 populations. Continental population abbreviations: SAM, Samoans (n = 250); EUR, Europeans (n = 253); AFR, Africans (n = 511); EAS, East Asians (n = 255); SAS, South Asians (n = 88); AMR, admixed Americans (n = 77). Supplementary Video 1 shows a rotating animation of this figure. (b) Scatterplots of the first six principal components from the principal-components analysis of the Samoans alone (n = 3,094) plotted against each other.
