Test Review

Huntington's disease is a fatal neurological disorder caused by a genetic mutation. It is usually diagnosed late in life. If a parent is diagnosed with the disorder, then there's a 50 percent chance that his or her children may possess the same genetic mutation.

1._______ testing enables relatives of someone with Huntington’s disease to ________their risk of developing Huntington’s disease in the future

• A. predictive, assess

• B. predictive, reduce

• C. diagnostic, reduce

• D. reproductive, assess

A potential benefit of pharmacogenomic testing is that it may lead to  _______ .for example, a doctor may be able to apply information from a patient’s genome to determine __________.

• A. New gene-related technologies, what gene variants the patient has in common with other people who share the same symptoms

• B. More individualized treatments. If a medication poses a risk to the patient

A population of frogs have moved into a new habitat. As a result of natural genetic variation, about 57 percent of the frogs are light green, and the other 43 percent are dark green. The graphic shows how the ratio of light green to dark green frogs then changes over the next several generations.

•Which best explains the change?

• A. The dark green coloring is more attractive to mates

• B. The allele for light green skin is recessive and so slowly disappears from the population

• ●

  C. The allele for light green skin is associated with a deadly disease

• D. The dark green frogs are better camouflaged, so they have better odds of escaping predators

Which most likely explains the increasing numbers of green beetles in the population over this time?

• A. Green beetles immigrate to the area during times of increased rainfall, while brown beetles emigrate to drier areas

• B. Green beetles prefer to lay eggs in a moist environment, so the extra rainfall gives them a larger area for breeding

• C. Green beetles are better camouflaged by vegetation, and more rainfall increases the amount of vegetation on the plot of land

• D. Green beetles are capable of drinking and storing more water than brown beetles during months when there is abundant rainfall

How does the diagram illustrate a mutation?

• A. The offspring inherited a different allele of the gene from each parent

• B. The gene the offspring inherited from its father is dominant

• C. The offspring inherited only one copy of the gene from each parent

• D. The gene the offspring inherited from its father changed

Will the mutation affect the organism's phenotype?

• A. It will if the trait the gene codes for is related to reproduction

• B. It will not because the change to the gene is so minor

• C. It will if the gene changes a protein that affects an observable trait

• D. It will not because the allele of the gene involved is dominant
