Which of the following could NOT cause a gene frequency change?

Question

Quizplus · Accepted Answer

Random mating, by definition, does not cause a change in gene frequencies within a population. It ensures that alleles are combined randomly, but does not itself alter the frequencies of those alleles. Other factors like migration, mutation, and selective pressures (such as an epidemic) can change gene frequencies by introducing new alleles, altering allele frequencies, or selectively removing individuals with certain genotypes from the population.
