Question

what are the two ways in which genetic drift has the most significant effect on a population? select an answer a. founder effect; horizontal gene transfer b. mutation; genetic bottleneck c. founder effect; genetic bottleneck d. genetic bottleneck; gene flow

Explanation:

Genetic drift's significant effects occur via founder effect (small group starts new population) and genetic bottleneck (drastic population reduction). Horizontal gene transfer, mutation, and gene flow are not genetic drift mechanisms. So option C is correct.

Answer:

C. founder effect; genetic bottleneck
