From: Local drift load and the heterosis of interconnected populations
The effect of the mutation raFte on heterosis. Higher deleterious mutation rates cause higher degrees of heterosis for s >> μ. (With μ >> s, nearly all populations are close to fixation for the deleterious allele, and the heterosis therefore is minimal.) The solid line corresponds to μ=10–6 (U=2 μn=0.02), the dotted to μ =10–5 (U=0.2), and the dashed line to μ =10–4 (U=2). Other parameters values are as in Fig. 2 with N=1000.
