Which of the following is NOT one of the Hardy-Weinberg equilibrium assumptions?

Which of the following is NOT one of the Hardy-Weinberg equilibrium assumptions?

• A. No gene flow
• B. No natural selection
• C. Random mutations
• D. Large population size

Answer: (C)

The correct choice identifies a principle that is not included among the assumptions of Hardy-Weinberg equilibrium. The Hardy-Weinberg model relies on certain key conditions to maintain genetic equilibrium in a population. These include the assumption that there are no forces causing allele frequencies to change. The assumptions that are part of this model include: - No gene flow: This means there is no migration of individuals into or out of the population, which could introduce new alleles or remove existing ones. - No natural selection: All individuals in the population have an equal chance of surviving and reproducing, thereby ensuring that allele frequencies remain constant over time. - Large population size: A sufficiently large population minimizes the effects of genetic drift, which can alter allele frequencies by chance events. In contrast, random mutations are not a specified assumption of the Hardy-Weinberg equilibrium. While mutations can introduce new alleles into a population and contribute to genetic variation, the model itself assumes that the allele frequencies are stable from generation to generation unless acted upon by outside forces. Therefore, the correct answer highlights that random mutations are not a condition that is assumed for a population to be in Hardy-Weinberg equilibrium.
