Figure H1.

The open markers show the numerical results of R as a function of s, while the curves show the theoretical predictions, based on the heuristic argument. The m rate of beneficial mutations is $\mu ={10}^{-4}$. The population size is $N={10}^{100}$ for α = 1,$N={10}^{10}$ for $\alpha =1.5$, and $N={10}^8$ for the Wright–Fisher model.
