Question

question 4 of 10
under which condition would a mutation have the most impact on allele frequency?
a. there is gene flow.
b. there is no gene flow.
c. the population is large.
d. there are individuals moving in and out of a population.

Explanation:

When there is no gene flow (immigration or emigration of alleles), mutations can accumulate and have a more significant impact on allele frequency. Gene flow (A and D) can introduce or remove alleles, reducing the mutation's impact. In a large population (C), genetic drift (which can be affected by mutations) has less impact as large populations are more stable. Without gene flow, the mutation's effect on allele frequency is more pronounced.

Answer:

B. There is no gene flow.
