Fig. 2.

Expected Wright–Fisher trajectories of allele A for different initial starting counts c₀, selection coefficients s, and effective population sizes N. Columns correspond to different initial starting frequencies $c_0/2N$ with $c_0/2N=0.01,0.1,$ and 0.25. The dominance parameter is set to h = ½ in all panels. Because the effects of mutation are negligible during the time periods we consider, we set $u_{Aa}=u_{aA}=0$.
