In a population fulfilling all the assumptions of the Hardy-Weinburg equilibrium, allelic frequencies:

A. will not change from generation to generation.

B. change randomly from year to year.

C. change infinitesimally from year to year.

D. change only in the females from year to year.

A. will not change from generation to generation.

Explanation:

For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:

-The population is large enough.

-Individuals of the population exhibit random mating.

-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.

Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
