The correct answer is: A.The gene pool remains constant.

Explanation:

In a population that is in Hardy-Weinberg equilibrium with no mutations, the gene pool remains constant. This means that allele frequencies do not change over time because there is no introduction of new genetic material through mutations.

Here’s why the other options are incorrect:

B.Genetic variation is always maintained: While genetic variation can be maintained in the absence of mutations, this doesn’t necessarily mean that variation will always stay constant over time b...
