What phenomenon would violate the conditions for Hardy-Weinberg equilibrium?
A)The population is isolated from other populations.
B)Females select males based on secondary sex traits.
C)The population is large.
D)No genotypes within the population have a reproductive advantage.
E)Genetic drift within the population does not change allele frequencies.

Question

Quizplus · Accepted Answer

Females selecting males based on secondary sex traits would violate the condition of random mating, which is required for Hardy-Weinberg equilibrium.

Answer: D
 No genotypes having a reproductive advantage would mean that there is no natural selection acting on the population, which is one of the conditions for Hardy-Weinberg equilibrium.

Note: Choices A, C, and E are all conditions that promote Hardy-Weinberg equilibrium, so they would not violate it.
