Figure 4.

Spread of immaculate white and blue egg in the parasite population when mutation occurs in spottiness, starting from an initial state that immaculate white and blue egg are absent in the parasite population. Initial frequencies are set arbitrarily as (h ₁₀, h ₂₀, h ₃₀, h ₄₀) = (0.225, 0.275, 0.2, 0.3) and (p ₁₀, p ₂₀, p ₃₀, p ₄₀) = (0, 0, 0.3, 0.2). Mutation probabilities and other parameters are the same as in Figure 2. Immaculate white, immaculate blue, white with spots and blue with spots is shown in solid gray, solid black, dashed gray and dashed black, respectively
