- CPopulation
4Genetic variation is
- AChange over time in the relative frequencies of allele variations

- CAll the individuals in a given area
5Select all that apply. Fitness is a measure of________
- AReproductive success contributed to the next generation
- BCompared to others in the same population and generation cohort
- CThe genetic change in a population
6The source of new alleles because of spelling changes in DNA
- AMutation
- BMigration
- CNatural selection
7Natural selection and genetic drift cause evolutionary change because______ (select all that apply)
- ASome alleles become more common in the next generation
- BSome alleles become less common in the next generation
- CIt is all about differential reproductive success
8A mechanism of evolution that causes a change in the allele frequencies of a population because of chance events not based on genetic traits
- AMigration
- BGenetic drift
- CNatural selection
9A mechanism of evolution in which new alleles are added to a population when new individuals enter from another location
- AMigration
- BGenetic drift
- CNatural selection
10Individuals that survive or reproduce at a higher rate because of their genetic traits defines __________ (select all that apply)
- ANatural selection
- BOne of the mechanisms of evolution

- ATrue
- BFalse
12Genetic drift has the biggest impact on small populations
- ATrue
- BFalse
13Founder effect is where a small number of individuals establish a new population
- ATrue
- BFalse
14The number of prairie chickens went from millions to fewer than 50, resulting in 30% of alleles being lost. This is an example of______. (Select all that apply)
- AGenetic drift
- BMigration
- CFounder effect
- DBottleneck
15Bottlenecks are a type of genetic drift that occurs because of a loss of a large percentage of population
- ATrue
- BFalse
16Mechanisms for genetic change are_______
- ANatural selection
- BGenetic drift

- ATrue
- BFalse

- ATrue
- BFalse
