The correct answer is: B.Allele frequencies remain constant.

Explanation:

In the context of Hardy-Weinberg equilibrium, if there is no migration, the principle assumes that allele frequencies remain constant over generations. This is because, in the absence of migration, the alleles in the population do not change due to the movement of individuals between populations. The population is expected to maintain a stable genetic structure under the right conditions, such as random mating, no mutation, large population size, and no selection.

The other options are incorrect because:

A.Allele frequencies will always change ove...
