Adaptation phases of a diploid population (with L = 3 loci). The curves represent the total population (top) and the part of the population with fit genotypes (individuals with lf ≥ 0.8). The vertical axes report the number of individual and the horizontal ones the number of generations. The initial populations has no fit genotype. The four graphs are expression of different selection strength (columns, from weakest on the left to strongest on the right) and of different percentage of asexual reproduction (rows, 0% asexual on top, 80% asexual on bottom). Top lines give the total amount of individuals in the population, while the bottom ones give the number of fit genotypes. The columns of the figures correspond to values of σ equal to 0.7 and 0.5, from left to right. Details of subfigures: (a) σ = 0.7 and 0% asexual; (b) σ = 0.5 and 0% asexual; (c) σ = 0.7 and 80% asexual; (d) σ = 0.5 and 80% asexual.
