Question

What is the primary statement of Hardy-Weinberg's principle?

Options

• Allele frequencies always increase in a population over time

• Natural selection always maintains constant allele frequencies

• Genetic variation decreases in populations that reproduce randomly

• Allele frequencies in a population remain constant from generation to generation in the absence of evolutionary forces

Answer 1

Hardy-Weinberg's principle explicitly states that allele frequencies remain constant across generations when no evolutionary forces act upon the population. This is the foundational concept describing genetic equilibrium in non-evolving populations.
