Fig. 5From: Fixation probability of a beneficial mutation conferring decreased generation time in changing environmentsa Examples of Eq. (30). The solid curve shows one example, and shaded curves show 20 other examples. The dashed line shows the mean selective advantage. The parameter values are s0 = 0.001, s mean  = 0.02, λ = 0.6, and σ = 0.001. b Comparison between the approximation and exact results when the selective advantage experiences stochastic fluctuations. The whiskers show 99% confidence intervals. The other parameter values are as in the top figureBack to article page
