What term correctly describes changes in allele frequency due to random inheritance of alleles from one generation to the next?

Genetic drift

Explanation:

Genetic drift can also be referred to allelic drift. This can be caused as a result of various reasons.

Let's take for instance in humans, a large population of black women in region A migrating to a white dominated region B. There is a high chance of these black women getting married to the white men in region B, and hence give birth to children with diverse allelic frequencies; over time these children born, continue to reproduce and might lead to very few totally white people.
