Answer :
Final answer:
Hardy-Weinberg equilibrium explains how allele frequencies stay constant in a population under specific conditions and how natural selection can disrupt this equilibrium.
Explanation:
Hardy-Weinberg equilibrium describes a theoretical situation where allele frequencies remain constant in a population if certain conditions are met, such as no evolutionary forces at play. The equilibrium can be disrupted by various factors, including natural selection, which favors specific alleles, causing the population to evolve over time. Therefore, evolving populations deviate from the expected values of the Hardy-Weinberg equation due to these evolutionary forces.
