Question

Which scenario is most likely to cause changes in allele frequencies in two populations of the same species?

Answer 1

Predators are present in one population but not in the other.

Step-by-step explanation:

My interpretation of the question is what situation would cause differences in allele frequencies between the two populations. If predators are present in only one of the two populations, then the safety of that population will be more threatened. While the other population's allele frequencies may remain unaffected, this population's allele frequencies will adjust according to which genotype a predator is most likely to act upon.
