Question

1-There is a population of individuals which are geographically isolated from other populations of their species. Their population mates randomly, has no net mutations in their genome, and is not subjected to natural selection pressures. However, their population is small, only 200 individuals. The gene for fur color in this population has two alleles in a dominant-recessive relationship, A and a. If allele A is currently at a frequency of 0.8 and allele a is at 0.2:

i. What do you think will happen to the frequency of these alleles in the population over time?

ii. What would be the mechanism responsible for any changes?

To earn full credit, you must briefly state what will happen to each allele (A and a) over time, include the frequency you would expect for each allele (anywhere from 0-1) and answer part ii.

2-
