Question

1. a biologist wants to measure the effect of gene flow between populations. which of the following investigations will allow her to accomplish this goal? an investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat an investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes an investigation that determines a change in allelic frequency of a wolf population by the immigration of a wolf from another population. an investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig

Explanation:

Gene flow is the transfer of genetic material between populations, which alters allele frequencies in the receiving population. The correct option directly measures this by tracking allelic frequency changes due to immigration of individuals from another population. Other options focus on non-population gene transfer, gene transfer timing, or mutation causes, not gene flow between populations.

Answer:

C. An investigation that determines a change in allelic frequency of a wolf population by the immigration of a wolf from another population.
