From: The importance of selection in the evolution of blindness in cavefish
The mutation rate of the blindness allele (u) affects the level of selection (s) required to produce blind populations. The format of this figure follows Fig. 2. As u increases, the amount of selection required to evolve blindness in the cave population decreases for small m, and blindness will evolve regardless of selection. The curves were calculated analytically with Q=0.01 and h=0.5
