Biased Gene Conversion, Study Populations, and Genetic Distances

(A) Depending on ancestral and derived states, SNPs can be classified as WW or SS (gray), SW (blue), and WS (red). Weak (A or T) alleles are represented by W and strong (G or C) alleles are represented by S.

(B) Study populations: Pygmy, YRI (Yoruba), Sandawe, Hadza, and CEU (Northern and Western European ancestry). Five high-coverage whole genomes were analyzed for each population.

(C) Genetic distances using population branch statistics. Mean values are shown for thee different types of SNPS: WW or SS (gray), SW (blue), and WS (red). Branch lengths depicted are for WW or SS SNPs.
