Numerical solutions for critical times starting at different initial frequencies of the MM genotype. With the parameter values for the combined system (ω=0.48,ν=0.52, Figure 2 C) we begin on the ++ - MM edge at different frequencies. The time required to reach MM frequencies >0.95 are plotted as the critical times. Starting with the frequency of MM genotypes of 0.6 (circles) only if d≥0.85 the system moves to the MM vertex. As the Medea lethality increases the all MM vertex can be reached by starting at lower frequencies of MM genotype. Starting at already high frequencies (0.9, open squares) the time to reach fixation quickly drops to the levels which are almost the same as that of complete Medea lethality. (Initial MM frequencies 0.6 (circles), 0.65 (squares), 0.7 (diamonds), 0.75 (triangles), 0.8 (inverted triangles)). For the recursions, Eqs. (1) were employed.
