Answer: allele frequencies do not change unless they are influenced by factors that cause evolution.
Explanation:
According to the Hardy-Weinberg studies of population genetics, the evolution occurs only when there is an alteration of some conditions such as mutation, migration, natural selection, a large populatuon or random mating. Taking this into consideration it can be said that allele frequencies change only if they are influenced by the previously mentioned factors.
