Question

2. You are a conservation biologist working on brown-striped snipes. Snipes are rare aquatic insects, and populations tend to be isolated from one another, because individuals migrate only infrequently from the pools where they hatch. As a result there is little gene flow, and populations tend to be small in size. a. How is genetic variation likely to be partitioned within vs. between populations? (3 pts) b. Is drift likely to play an important role in altering population allele frequencies? (3 pts) c. If migration increased among populations how would this affect genetic variation within populations and between populations? (3 pts) d. Due to a rare but large migration event, the size of one population increases 4-fold. Will the potential for genetic drift increase, decrease or remain unchanged in the population? (3 pts)
