Extended Data Figure 2: Distribution of fixed differences.
From: Altitude adaptation in Tibetans caused by introgression of Denisovan-like DNA
The left panel is the distribution of fixed differences between two haplotype groups under a scenario of selection on a de novo mutation (see Methods), and the right panel is the distribution under a scenario of selection on standing variation (see Methods) for a region of size ∼32.7 kb. The initial frequency of the selected allele in the SSV model is 1%. Each row of panels corresponds to different selection strengths (2Ns) from 200 to 1,000. The red lines mark the number of fixed differences observed between the two haplotype classes in the real data for the given window size.
