GMR plotted against the isogenetic SD of fitness due to initial noise, i.e., perturbation to the initial conditions. The GMR was computed following the same procedure as in Fig. 5, for the MR case, whereas the fitness variance was computed by distributing the initial condition for \(x_i\) with the variance \(\sigma\), which is either \(10^{-2}\) or \(10^{-1}\). The data correspond to the equivalent mutation rates as used in Fig. 5. The average over 50 samples is plotted. The error bar denotes the SD over them
