Relationship between V
( i ) and V
( i ). As described in the Method section of the text, V
(i) was computed as the variance of the distribution of Sign(x
) over 200 runs for an identical genotype, while V
(i) was computed as a variance of the distribution of over 200 individuals, where was the mean over 200 runs. σ = 0.1 (a), 0.05 (b), 0.01 (c), and 0.001 (d). The plot of (V
(i) and V
(i)) for all genes i at the 300th generation: Target genes as red ▢, and nontarget genes as blue +.
