Expert Solution
Step 1
Introduction
The Hardy-Weinberg principle states that in a large and isolated population, the frequency of alleles (versions of a gene) and the distribution of genotypes (the combination of alleles) will remain constant from generation to generation in the absence of any evolutionary forces such as mutation, migration, selection, or genetic drift.
