Expert Answer

Step 1

According to the Hardy-Weinberg equilibrium, the frequencies of the alleles and genotypes in a population remain the same for various generations. Generally, allele and genotype frequencies change over time due to evolution, so a population that follows Hardy-Weinberg equilibrium does not evolve. The assumptions made for Hardy-Weinberg equilibrium are no mutation, no gene flow, no mating, and no natural selection.

Step 2

According to the Hardy-Weinberg equation-
