Microevolution Quiz

Question 1

The sickle cell allele is more likely to have higher prevalence in populations where:

  • Malaria is not present
  • Antibiotics are not available
  • Malaria is present
  • Antibiotics are available

Question 2

A storm uproots 60% of the trees in a population. This is an example of:

  • Gene flow
  • Genetic drift
  • Gene pool
  • Natural selection

Question 3

What sorts of effects do new mutations have on the individuals that inherit them?

  • Mutations disrupt the normal development of an organism. They produce phenotypes that are bizarre and have a poor chance of survival.
  • Mutations do not affect proteins or alter phenotypes; they only affect gene sequences (DNA).
  • Mutations can have a wide range of effects on proteins and therefore phenotypes. They may have no effect, a negative effect, or a positive effect on survival, growth, mating success, etc.

Question 4

Modern HIV therapy controls HIV infection through what strategy?

  • Several different drugs are used that target different viral enzymes; if the virus evolves resistance to one drug, a different set of drugs is used.
  • A single drug that stops viral replication is paired with another drug that prevents the virus from mutating so that it cannot evolve resistance.
  • A single very effective drug stops viral replication by targeting a key viral enzyme that is indispensable to the virus.

Question 5

______________ can occur only if there are two or more separate gene pools that are exchanging individuals (through migration) or genes.

  • genetic drift
  • gene flow
  • natural selection
  • mutation

Question 6

Each year a gardener saves seeds from those tomato plants that produce the juiciest fruits. She uses these seeds to plant the next year’s crop of 20 plants. Over time, the gardener develops her own special variety of very juicy tomatoes. This is best described as an example of…

  • mutation
  • artificial selection
  • genetic drift
  • sexual selection
  • natural selection

Question 7

Which gene pool has changed through some process of microevolution?

  • A mouse population (about 10,000 mice total) starts with 99% of the mice tan and 1% white; after 20 years 70% are tan and 30% are white.
  • Your cells express different genes today than they did when you were born.
  • A moth population increases from 3,000 individuals to 33,000 individuals over a period of favorable weather.

Question 8

A population of pond snails has two genetically determined types: one with a black stripe on its shell and one with a plain brown shell. Evidence indicates that there is absolutely no difference between the two snail types in terms of their fitness: each type survives, grows, and mates with the same average level of success. Over time, black-striped snails become more or less common in a population due to chance events. At one point, for example, the pond nearly dries up and the few surviving snails happen to be mostly black-striped. This evolutionary change is the result of…

  • natural selection
  • mutation
  • genetic drift
  • sexual selection
  • gene flow

Question 9

Humans are the only primate species in which mammary glands (breasts) remain large and prominent throughout adulthood. Other primates’ mammary glands swell only when they are nursing offspring; scientists are not sure why human females have noticeable breasts on a permanent basis. One hypothesis is that they increase a female’s ability to attract mates. If so, this would be an example of a trait favored by…

  • artificial selection
  • genetic drift
  • sexual selection
  • gene flow
  • natural selection
