Mutation-selection balance The equation of Exercise 41 can be extended to account for a deteriousmutation that destroys the bacterial strain of interest. The differential equation becomes ( d p )/( d t ) = s p ( 1 - p ) - μ p p ( 0 ) = p 0 where μ is the mutation rate and μ > 0 (see Exercise 7.2 .19 ) . Solve this initial-value problem for s ≠μ.
