) Suppose an island on the Gulf Coast of Florida, where the sand is light, is colonized by a population of Peromyscus polionotus that is fixed for the dark colored allele at MC1R. Further assume that this population is of size 10,000. Imagine an individual who is heterozygous for the light allele moves into the population. This individual then mates with one of the dark colored individuals. How many generations will be required for the light colored allele to reach frequency 90% in the population
