Evaluation of the STR catalog for population genetics. (A) Genetic diversity of the 10% most heterozygous autosomal loci in different populations. (Yellow) European; (red) African; (blue) East Asian. The mean heterozygosities (dot) of the African subpopulations consistently exceed those of the non-African subpopulations. The whiskers extend to ±1 standard deviation. See Supplemental Table 3 for population abbreviations. (B) STRUCTURE clustering based on the 100 most polymorphic autosomal STR loci. Each subpopulation clusters tightly by geographic origin. Color labels as in A. (C) Average STR heterozygosity as a function of chromosome type. Bars denote the standard error.
