Figure 2.

Fitness estimated through lifetime reproductive output for the multi- (a,b) and single-locus scenarios (c,d) as a function of genotype across 50 replicated simulation runs at fishing mortality F = 0.4. Fitness functions are shown separately for the non-harvested population at its dynamic and adaptive equilibrium (a,c) and for the first 10 years of fishing (b,d). For the multi-locus scenario, genotypes are expressed by the sum of allelic values (0 or 1) across 10 diploid loci. For the single-locus scenario, genotype is 0, 1 (heterozygote) or 2, and the genotype expression depends on the sex. 95% CIs are indicated by vertical lines. In the single-locus scenario, females are indicated by red and males by blue. (Online version in colour.)
