Composition of the number of mutations at each recurrently mutating locus. This figure is for a fixed backward/forward ratio (v/μ = 1) and a fixed sample size (n = 100). The composition of the number M of forward mutations mapped on a genealogy, among recurrently mutating loci showing polymorphism, is shown under various forward mutation rate (θμ) and the selection intensity (σ). Panels A, B, and C give results with σ=0,σ = − 10+ 3/2, and σ = − 10+ 5/2, respectively. In each panel, a horizontal bar shows the composition for a value of θμ specified on the left. In each horizontal bar, white, red, blue, yellow, green and black rectangles represent the proportions of mutation loci with M = 1, 2, 3, 4, 5–9, and 10-, respectively.
