The correct answer is: B.Being in Hardy-Weinberg equilibrium.

Explanation:

In Hardy-Weinberg equilibrium, one of the key assumptions is that no mutations occur. If mutations were to happen, new alleles would be introduced to the gene pool, potentially affecting allele frequencies. So, being in Hardy-Weinberg equilibrium inherently means that mutations do not alter allele frequencies in the population.

Here’s why the other options are incorrect:

A.Small population size: A small population is more likely to experience genetic drift, where allele frequencies can fluctuate rando...
