Question

Quizplus · Accepted Answer

The Hardy-Weinberg principle is useful because it provides a baseline expectation for allele and genotype frequencies in a population not undergoing evolution. It identifies factors such as mutation, gene flow, genetic drift, non-random mating, and selection that can cause deviations from this expectation, thereby changing allele or genotype frequencies.
