Relationship between Vg(i) and Vip(i). As described in the Method section of , Vip(i) was computed as the variance of the distribution of Sign(xi) over L runs for an identical genotype, while Vg(i) was computed as a variance of the distribution of over N individuals, where was the mean over L runs. Here we adopted N = L = 1000, instead of 200 in . σ = 0.09 (blue *) and 0.03 (red +). The plot of (Vg(i) and Vip(i)) for all genes i over 55-65th generations, where we have plotted only those genes with Vg(i) > .0002, as the those with smaller than that may have little accuracy in estimating Vg(i).
