Natural selection is the primary force responsible for changes in allelic frequency of deleterious mutations because it tends to eliminate harmful alleles from a population. Genetic drift is the primary force responsible for changes in allelic frequency of neutral mutations because it causes random fluctuations in allele frequencies, especially in small populations, and affects alleles that do not confer a selective advantage or disadvantage.
