Figure 4.

Concentration of mutant genomes Y_m as a function of passage (γ_m/γ_w = 0.4, μ = 10^-4). Concentrations at passage 0 were y_ww = y_mm = 0.5, y_wm = y_mw = 0. Trajectories labeled "phenotypic hiding" were generated from equations (2a)–(2d). The trajectory labeled "standard quasispecies model" was generated from iterating = [γ_m (1 - μ) Y_m + γ_w μ(1 - Y_m)]/[γ_mY_m + γ_w(1 - Y_m)].
