GC-Biased Gene Conversion Modifies the Site Frequency Spectra of Diverse Human Populations
Pygmy (A), YRI (B), and Sandawe (C) populations have an excess of low-frequency derived alleles relative to Hadza (D) and CEU (E) populations. Probability distributions sum to one for each type of SNP: WW or SS (gray), WS (blue), and WS (red). Site frequency spectra of SW SNPs are left-shifted and site frequency spectra of WS SNPs are right-shifted.
