B. Genetic drift

C. Migration

D. Natural Selection

E. All of the above change both allelic and genotypic frequencies

Solutions

Expert Solution

Answer:

Correct Option is E: All of the above change both allelic and genotypic frequencies

Assortative mating is a type of non-random mating, where individuals having similar phenotypes mate with each other more frequently than would expected under a random mating pattern.
This evolutionary agent violates the Hardy-Weinnerg equilibrium and it can change both allel and genetic frequencies in a population.
According to the principle of Hardy-Weinnerg equilibrium Genetic drift,Migration and Natural Selection are all against the principle which causes both allel and genetic frequencies to chang in a population.
Hardy-Weinnerg equilibrium states that in a population the allelic frequency and the genotype frequency will remain constant from generation to generation if there is no mutation, no natural selection, no gene flow, large population size and random mating among the individuals in a population.
