Fig 1. — Endless coevolutionary chase between the sexes. Parameters: μ = 10⁻⁵, r = 0.5, Δ = 10⁻⁶, v_m,j = 1, Ψ_ij = exp[−(i − j)²/(2α²)] with α = , and w_f,i = exp[−S(P_i − P_opt)²] with S = 1, P_opt = 0.4. Initial genotype frequencies are Φ₅₆ = 0.99, Φ₅₅ = 0.01. The equilibrium value of P̄ is ≈0.86.
