Figure 4From: Phenotypic effect of mutations in evolving populations of RNA moleculesDependence of the phenotypic mutation fractions and of the average selective coefficients on the mutation rate μ - Optimized population. The phenotypic mutation fractions p and q increase monotonically as μ grows. Below the error threshold they behave as a power-law of μ, to a good approximation. The average selective coefficients σ p and σ q show little variation with μ. The inset shows the ratio between the fraction of beneficial and deleterious mutations. The straight line serves as a guide to the eye.Back to article page
