Figure 6.—

Effects of linkage on the fixation probability of the coadapted haplotype A₁B₁ in a subdivided population. Simulation results are illustrated for c = 0.00005, 0.005, and 0.5 (i.e., free recombination). Other parameters are N = 1000, L = 10 (N_T = 10,000), s = 0.01, and T = 100. The results recapture the preceding observation that the fixation probability is maximized by an intermediate degree of linkage, roughly when c = s/2 (Takahasi and Tajima 2005), although the effect of linkage becomes less pronounced as the migration rate becomes smaller.
