Review Questions- Evolution and Population Genetics

A population of 28 individuals has the following genotypes:

• 12 AA

• 10 Aa

• 6 aa

1.  What is the gene frequency of A?

2.  What is the gene frequency of a?

3.  Suppose that the frequency of A in a population is 0.46. What will happen to the frequency of “A” in the next generation if mating is random, there is no selection, no mutation, and no migration?

1. It will increase.

2. It will decrease.

3. It will remain the same.
