Figure 3.
Site-frequency spectra of polymorphisms identified at 20 autosomal regions sequenced herein. Current data set is compared with HapMap SNPs (A) globally and for similar populations: (B) Mandenka (Yorubans), (C) French Basque (CEU), and (D) Han Chinese (Han Chinese). SNPs are classed into those found both in the current and HapMap databases (blue), in the current database only (red), or in the HapMap database only (yellow). The number of SNPs identified per population is scaled proportionally; note that Africans contain more SNPs than non-Africans.
