Final answer:
Genetic drift is the random change in allele frequencies in a population over generations.
Explanation:
Genetic Drift
Random changes in the allele frequency of a population between generations is defined as genetic drift. It is a mechanism of evolution that occurs due to chance events causing certain alleles to become more or less common in a population over time.
For example, in a small population, if a few individuals have more offspring than others simply by chance, their alleles will become more prevalent in the next generation, causing a change in allele frequencies.
