Multiple Choice
According to the Hardy-Weinberg principle, what happens to allele frequencies in a population that is not subject to evolutionary forces?
A
They remain constant over generations.
B
They decrease due to genetic drift.
C
They increase due to natural selection.
D
They fluctuate randomly.
Verified step by step guidance
1
Understand the Hardy-Weinberg principle: It states that allele frequencies in a large, randomly mating population remain constant from generation to generation in the absence of evolutionary forces.
Identify the evolutionary forces that can affect allele frequencies: These include natural selection, genetic drift, mutation, migration, and non-random mating.
Recognize that the problem asks about a population not subject to these evolutionary forces, meaning none of the factors that can change allele frequencies are present.
Apply the Hardy-Weinberg principle to the scenario: Since no evolutionary forces are acting on the population, the allele frequencies should remain constant over generations.
Conclude that the correct interpretation of the Hardy-Weinberg principle in this context is that allele frequencies remain constant, which aligns with the first option provided in the problem.
