Chapter 20: Genetic and Genomic Variation
Multiple Choice
Identify the choice that best completes the statement or answers the question.
____ 1. What is the main purpose of population genetics?
A. Determining the factors that allow allelic frequencies to change over time
B. Determining the geographic origins of specific genetic-based disorders
C. Assessing the effects of assortive mating on natural selection and evolution
D. Assessing the differences between race and ethnicity for susceptibility and
resistance to infectious diseases
____ 2. What factors could increase genetic diversity in a particular population?
A. Genetic drift
B. The population effect
C. The bottleneck effect
D. Increased number of haplotypes
____ 3. What criteria must a population meet in order to stay in Hardy–Weinberg equilibrium?
A. Random mating, no migration, and no mutation
B. Founding commonalities and no haplotype differences
C. Assortative mating, migration, and frequent mutation
D. Limited procreation, no diet change
____ 4. What pieces of genetic information tend to be passed down from generation to generation with the
least variation?
A. Mitochondrial DNA
B. Nuclear DNA
C. Ribosomal DNA
D. Histone proteins
____ 5. Why is it important to consider population genetics?
A. Natural selection can increase genetic diversity.
B. Accurate assessment of a person’s ethnicity can be identified from DNA.
C. Disease risk can vary as a result of the geographic origin of one’s ancestors.
D. Knowing ethnicity allows accurate prediction of Huntington disease risk.
____ 6. Which practice is most likely to result in a change in the Hardy–Weinberg equilibrium of a
population or geographic area?
A. Random mating from within the established population
B. Geographic isolation of the established population
C. Assimilation of immigrants into the existing population
D. Preponderance of autosomal-dominant traits in the existing population
____ 7. A group of eight space travelers, four men and four women, settled on the planet Zebulon. Their
descendants had a very high rate of the autosomal-dominant disorder moonophilia distractens. What
factor could explain this phenomenon?
A. Equal exposure to an environmental mutagen
, B. Hardy–Weinberg equilibrium
C. Variable expressivity
D. Founder effect
____ 8. A small group of people left their homeland and set sail for a tropical island. They settled there, and
their descendants lived for many generations. Unfortunately, a relatively high proportion of this new
population is afflicted with an autosomal-recessive disease. What would explain this?
A. They encouraged immigration of people from the mainland.
B. An unidentified environmental radiation source was present on the island.
C. One of the original group members had the gene mutation from conception.
D. Their lack of genetic diversity made them more vulnerable to new mutations.
____ 9. The Black Death was a pandemic spreading across Europe between 1348 and 1350. Estimates state
that 30% to 60% of Europe’s population died from the Black Death. If we look at Europe’s
population before the pandemic and compare it to the population several generations later, what are
we likely to find?
A. More genetic diversity in later generations
B. Less genetic diversity in later generations
C. Less genetic diversity in earlier generations
D. The same degree of genetic diversity in later as in earlier generations
____ 10. Why are people of Ashkenazi Jewish descent more likely to be carriers of the mutations that cause
Tay–Sachs and Gaucher disease?
A. The environment of Eastern Europe increased their risk of developing a mutation.
B. The common diet shared by these people has reduced their genetic diversity.
C. Bottleneck effects have reduced the genetic diversity in this population.
D. Being heterozygous for these diseases allowed them to survive cholera.
____ 11. Which term refers to a random change in allele frequencies, not based on natural selection?
A. Population bottleneck
B. Genetic drift
C. Founder effect
D. Migration effect
____ 12. Which statement regarding genetic diversity is most accurate?
A. Larger genes are more likely to display diversity than small genes.
B. Genetic diversity is significant only when a population is isolated.
C. Genetic disorders are more common in populations that have greater genetic
diversity.
D. Population bottlenecks result in loss of alleles that provide minimal selection
advantage.
