Hard· +4 / −1
Statement I: According to the Hardy-Weinberg principle, in a large, randomly mating population with no mutation, migration, selection, or genetic drift, allele and genotype frequencies remain constant across generations, following .
Statement II: A significant, sustained deviation of a population's observed genotype frequencies from Hardy-Weinberg equilibrium expectations is strong evidence that one or more evolutionary forces (such as natural selection or genetic drift) are actively acting on that population.
In light of the above statements, choose the correct answer.
