Understanding Hardy-Weinberg Principles

What is the Hardy-Weinberg Principle primarily used to describe?

• The process of natural selection

• The genetic equilibrium in a population

• The mutation rate in a population

• The migration patterns of species

Which of the following is a condition that must be met for a population to be in Hardy-Weinberg equilibrium?

• High mutation rate

• Non-random mating

• Large population size

• High migration rate

If the frequency of allele A is 0.6, what is the frequency of allele a in a population in Hardy-Weinberg equilibrium?

• 0.4

• 0.6

• 0.3

• 0.5

• 0.21

• 0.42

• 0.49

• 0.09

In a population, the frequency of the homozygous recessive genotype (aa) is 0.09. What is the frequency of the recessive allele (a)?

• 0.3

• 0.09

• 0.81

• 0.7

Which of the following statements is true about allele frequencies in a population at Hardy-Weinberg equilibrium?

• Allele frequencies change rapidly over time.

• Allele frequencies remain constant over generations.

• Allele frequencies are always equal.

• Allele frequencies depend on the environment.

If a population is in Hardy-Weinberg equilibrium, what can be inferred about the population?

• It is evolving.

• It is not evolving.

• It has a high mutation rate.

• It is undergoing natural selection.

• 0.64

• 0.16

• 0.32

• 0.04

In a population, the frequency of allele A is 0.5. What is the expected frequency of the AA genotype in Hardy-Weinberg equilibrium?

• 0.25

• 0.5

• 0.75

• 1.0

Which of the following factors can disrupt Hardy-Weinberg equilibrium?

• Random mating

• Genetic drift

• Large population size

• No mutation
