Answer 1

Mutation, Gene flow, non-random mating, genetic drift, and selection

Question 2

What aspects does a non-evolving population have?

Very large population (no genetic drift). No migration (no gene flow in or out) No mutation (no genetic change). Random mating (no sexual selection) No natural selection (everyone is equally fit)

Question 3

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 9% of all butterflies are white. Given this simple, information, which is something that is very likely to be on an exam, calculate the following: The frequency of the “aa” genotype. The frequency of the “a’’ allele. The frequency of the “A” allele. The frequencies of the genotypes “AA” and “Aa”
