In areas with primarily dark-colored substrate, dark-coat mice have a selective advantage over light-coat mice. Therefore, mice with one or more copies of the dominant Mc1r D allele have a selective advantage over mice with two copies of the Mc1r d allele. Even small selective advantages can have a profound effect on allele frequencies in a population if given enough time.
15)In a population of 500 light-coat individuals (dd), an individual is born with a mutation (D) in one of their two copies of the Mc1r with the effect of producing a dark-coat phenotype. What is the initial frequency of the D in this population?
