Biology

The correct answer is: B.The allele frequencies would fluctuate.

Explanation:

When migration occurs regularly, individuals from different populations interbreed, introducing new alleles or changing the frequency of existing alleles in the population. This gene flow tends to cause fluctuations in allele frequencies over time, as new genetic material is continuously introduced, and populations mix. These changes prevent the allele frequencies from stabilizing or staying fixed.

The other options are incorrect because:

A.Allele frequencies would stabilize over time: Migra...
