Figure 1From: The relationship between the error catastrophe, survival of the flattest, and natural selectionPhenotype Fraction vs the selection coefficient (s). The amplification factors of the master and mutant phenotype are Am = 10 and Ak = 2, respectively. In both cases the degradation factor is D = 1, and the sequence length is ν = 20. The selection coefficient is evaluated as in equation 6.Back to article page
