Problem:
Question 1: What is the difference between a stable equilibrium and a neutral equilibrium in population genetics? What kind of data would you need to collect about a population to establish that it is in a stable equilibrium, as opposed to a neutral one. Describe two different population genetic scenarios that are expected to cause a population to reach an equilibrium in allele frequencies. For each scenario, explain what population genetic mechanisms are operating, and what kind of equilibrium is obtained in each case and why.
Question 2: Describe two different population genetic scenarios under which natural selection is not expected to achieve perfect adaptation. For each scenario, explain what population genetic mechanisms are operating, and how they lead to imperfect adaptation. Give an example of one of the scenarios.
Any help would be greatly appreciated!
