Figure 6. Numerical simulations of the evolutionary dynamics that show the four behaviors in Figure 5A.

The sterility allele is recessive, and we consider single mating (n = 1). For each of the four panels, we use the initial conditions: A: $X_{AA,0}=1-{10}^{-3}$ and $X_{AA,1}={10}^{-3}$; B: $X_{aa,1}=1-{10}^{-3}$ and $X_{aa,0}={10}^{-3}$; C: $X_{AA,0}=0.27$ and $X_{aa,0}=0.73$ (lower curve), and $X_{AA,0}=0.26$ and $X_{aa,0}=0.74$ (upper curve); D: $X_{AA,0}=1-{10}^{-2}$ and $X_{AA,1}={10}^{-2}$ (lower curve), and $X_{aa,1}=1-{10}^{-2}$ and $X_{aa,0}={10}^{-2}$ (upper curve). We set r₀ = 1. A: Parameters p₀ = 0.5, r_1/2 = 1.0869, and r₁ = 1.1521. B: Parameters p₀ = 0.5, r_1/2 = 1.0669, and r₁ = 1.1321. C: Parameters p₀ = 0.5, r_1/2 = 1.0669, and r₁ = 1.1521. D: Parameters p₀ = 0.5, r_1/2 = 1.0869, and r₁ = 1.1321.
