Which practice is most likely to result in a change in the hardy–weinberg equilibrium of a population or geographic area?

a. assimilation of immigrants into the existing population
b. random mating from within the established population
c. geographic isolation of the established population
d. preponderance of autosomal-dominant traits in the existing population

Correct answer is (a). Assimilation of immigrants into the existing population.

Explanation:

The frequency distribution will not change from generation to generation once a population is in Hardy-Weinberg equilibrium. However, on assimilation of immigrants into the existing population, the equilibrium will definitely change.

the answer is the last option or letter d)
