Fig. 3.—

Simulated derived allele SFS (normalized by the frequency of singletons) for sites in p ₂ not being dependent on the allelic state in p ₃ for a model of constant N_e, n  = 50 chromosomes and no ongoing gene flow (number of alleles only shown up to n  = 30). Thick solid line is the expected SFS $s_x=\theta \frac{1}{x}$. Solid lines denoted by parameter nd represent the SFS for sites simulated under the model of ancestral structure, dotted lines denoted by parameter f represent the SFS for sites simulated under the model of recent admixture.
