Figure P23.3

Figure P23.3. The cost of reducing the mutation rate (green) is counterbalanced by the mutation load (blue). Overall fitness is the product of these two factors (red). (Left arrow) Mutation rate that maximizes overall fitness; (right arrow) mutation rate that will evolve with sexual reproduction, assuming ten equal-sized chromosomes.
