Question 4 Multiple Choice (Single Answer)

  2. Gene flow
  3. Non-random mating
  4. Natural selection
  5. All of the above
Question 6 Multiple Choice (Single Answer)

The Hardy-Weinberg equilibrium is a useful concept in population genetics because it:

  1. Provides a baseline for comparing real populations

  1. p^2
  2. 2pq
  3. q^2
  4. p + q

  1. 0.36
  2. 0.48
  3. 0.16
  4. 0.24
Question 9 Multiple Choice (Single Answer)

  1. Yes
  2. No
  3. Cannot be determined
Question 10 Multiple Choice (Single Answer)

Which of the following is NOT an assumption of the Hardy-Weinberg equilibrium?

  2. Allele and genotype frequencies remain constant over time
  3. Allele and genotype frequencies oscillate around a mean value
  4. Allele and genotype frequencies are randomly distributed
Question 12 Multiple Choice (Single Answer)

In a population at Hardy-Weinberg equilibrium, the frequency of the homozygous recessive genotype is:

  1. p^2
  2. 2pq
  3. q^2
  4. p + q
Question 13 Multiple Choice (Single Answer)

  1. 0.24
  2. 0.36
  3. 0.48
  4. 0.72
