The correct answer is: A.changes in allele frequencies

Explanation:

The Hardy-Weinberg equilibrium is a principle used in population genetics to measure whether allele frequencies in a population are stable, meaning there is no evolution occurring. It assumes no changes in allele frequencies over time unless influenced by factors like mutation, natural selection, genetic drift, or gene flow.

Here’s why the other options are incorrect:

B.Numbers of mutations: The Hardy-Weinberg equilibrium doesn’t specifically measu...
