Microevolution & Patterns of Natural Selection

Multiple Choice

True or False: Microevolution happens WITHIN a population.

• true

• false

Multiple Choice

True or False: Microevolution does not result in a change in allele frequencies within a population.

• true

• false

Multiple Select

Which of the following processes can occur which causes evolution to happen? (Select all that apply)

• Migration

• Nonrandom Mating

• Migration

• Natural Selection

• Genetic Drift

Multiple Choice

Which process of microevolution happens as a result of small populations? (Hint: look at your notes)

• Mutation

• Genetic Drift

• Nonrandom Mating

• Migration

Multiple Choice

True or False: Mutations are not random.

• True

• False

Multiple Choice

True or False: Mutation always result in a trait that is beneficial.

• True

• False

Multiple Choice

 

The table shows the survival rate of two types of beetles in the same environment over a period of three years.   Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have

• Green beetles are more fit for their environment than brown beetles

•  brown beetles are undergo more unfavorable mutations than green beetles

Multiple Choice

How does population size influence the degree of genetic drift which the population experiences?

• Large populations are more susceptible to drift because the presence of many individuals

  makes it more likely that random traits will evolve in the next generation

• Large populations are more susceptible to drift because there is more overall genetic

  variation, which can cause some genes to pair up in a deleterious manner

• In small populations there is an increased chance of random changes in allele frequency

  due to sampling errors from one generation to the next

• There is not a significant relationship between population size and genetic drift
