Figure 1. — (a) Concave fitness curve given by equation (2.1) for M = 50. (b) Schematic representation of the three equilibria for M = 50 and varying μ, showing E₁ (black), E₂ (red) and E₃ (blue). Normalized mean fitness (mean fitness divided by mean BPI fitness) of (c) genotypes (black line); (red line) and (blue line), and (d) genes (black line) and (red line), for fixed values of p_A. (e) Trajectories of genotype frequencies through time and (f) mean genotype fitness (scaled to maximal fitness of unity for no mitochondrial mutants), from an initial frequency p_A = 0.01 at generation 100. Parameter values: M = 50, μ = 0.01.
