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
