Fig. 2From: Using the Neandertal genome to study the evolution of small insertions and deletions in modern humansDerived allele frequency spectra (AFS) of indels in Africans from the 1000 Genomes dataset. The AFS for non-African populations is shown in Additional file 1: Figure S1. Wilcoxon rank sum tests (two-sided) show that the frequency distributions of insertions and deletions differ significantly for all populations (p < 2.2e-16)Back to article page
