Population fraction for two competing quasispecies as a function of genotypic mutation rate. The figure shows the population fraction obtained from equations 12 at the steady state as a function of genotypic mutation rate. Colored lines show the frontiers between the three phases in which alternate quasispecies dominate. In phase I and III, quasispecies A is selected, whereas in phase II, quasispecies B is selected. The amplification factors of quasispecies A are AAm = 10 and AAk = 6. Those of quasispecies B are ABm = 8 and ABk = 5. The value of ai, which determines the effect of the genotypic mutation rate on the phenotypic mutation rate are aAm = 15, aAk = 0, aBm = 7, and aBk = 0.
