Mutational parameters. (ΔMw, per-generation change in relative fitness (95% CI); VM, per-generation mutational variance (95% CI); Umin, Bateman–Mukai estimate of genomic mutation rate for relative fitness; E[a]max, average effect of a new mutation on relative fitness. See §2 and the electronic supplementary material text for details of calculations.)
