The correct answer is: B.It prevents new genetic variations from appearing.

Explanation:

In Hardy-Weinberg equilibrium, the assumption is that no mutations occur. This is important because mutations are the source of new genetic variations in a population. If mutations were happening, new alleles could be introduced, potentially changing allele frequencies and disrupting the equilibrium.

Here’s why the other options are incorrect:

A.It increases genetic diversity over time: Mutations actually increase genetic diversity, but in Hardy-Weinberg ...
