This table summarizes the average global ancestry percentages for each of the sampled populations found using ADMIXTURE.⁴⁷ Admixture proportions in CO and CR were estimated using supervised model with reference populations. Admixture proportions in other populations were inferred using an unsupervised model (see Subjects and Methods). Population abbreviations are as in Figure 1.
