In which type of population is genetic equilibrium most likely to occur according to the Hardy-Weinberg Principle?

• A. A large population with random mating and no selection
• B. A population undergoing natural selection
• C. A small population with frequent mutations
• D. A population with high migration rates

Answer: (A)

Verified step by step guidance

1. Understand the Hardy-Weinberg Principle: It describes a model where allele frequencies in a population remain constant from generation to generation in the absence of evolutionary influences.
2. Identify the conditions required for genetic equilibrium according to the Hardy-Weinberg Principle: These include a large population size, random mating, no mutations, no migration, and no natural selection.
3. Evaluate each option based on these conditions: A large population with random mating and no selection fits the criteria for genetic equilibrium.
4. Consider why other options do not meet the Hardy-Weinberg conditions: Natural selection, frequent mutations, and high migration rates introduce changes in allele frequencies, disrupting genetic equilibrium.
5. Conclude that genetic equilibrium is most likely in a large population with random mating and no selection, as it meets all the Hardy-Weinberg conditions.
