- 1. Multiple Choice
A type of genetic drift in which small groups of organisms separate from a larger population and form new small colonies.
Gene Flow
Founder Effect
Natural Selection
Artificial Selection
- 2. Multiple Choice
This is one of the mechanisms of evolution; it occurs when individuals move into or out of a population. It is also known as migration.
Gene flow
Founder effect
Natural selection
Microevolution
- 3. Multiple Choice
This is one of the mechanisms of evolution; it is a continuous process in which organisms with traits that make them better-adapted to their environment are more likely to survive and reproduce than organisms without such adaptations
Directional selection
Microevolution
Gene flow / genetic drift
Natural selection
- 4. Multiple Choice
This is a pattern of natural selection where one extreme form of a trait is more advantageous than the average or the opposite extreme; as a result, this trait in the population tends to evolve towards that one extreme
Directional selection
Disruptive selection
Stabilizing selection
Forward selection
- 5. Multiple Choice
This occurs when a large population is drastically reduced by an event such as a natural disaster; the population's new gene pool only contains alleles from the survivors
Founder effect
Bottleneck effect
Meteor effect
Natural selection
- 6. Multiple Choice
This is the process that ultimately creates new variations and changes in DNA; leads to the creation of new alleles
Mutation
Microevolution
Natural selection
Gene flow / genetic drift
- 7. Multiple Choice
This is a pattern of natural selection in which the average (or intermediate) form of a trait is the most advantageous, and so a population evolves away from the extremes and toward the average
Disruptive selection
Directional selection
Stabilizing selection
Middle selection
- 8. Multiple Choice
What do we call a change in then allele frequency over time?
Evolution
Adaptation
Extinction
Environmental influences
- 9. Multiple Choice
Since the 1800s humans have stopped burning coal, and the trees have returned to their original color. Which moth will be more successful in this environment?Dark mothLight mothBoth will be equally successfulNeither will be successful - 10. Multiple Choice
What mechanism of evolution occurs when allele frequencies change over generations due to random chance?
Genetic Drift
Mutation
Natural Selection
Gene Flow
- 11. Multiple Choice
What is the difference between genetic drift and natural selection. SELECT ALL THAT APPLY
Natural Selection creates adaptations and Genetic Drift does not.
Natural Selection is not random and Genetic Drift is.
Natural Selection passes on any trait and Genetic Drift passes on specific traits.
Natural Selection happens over a single generation and Genetic Drift happens over multiple generations.
- 12. Multiple ChoiceWhat is a gene pool?a place where genes can swimchange in a speciesall the genes in a populationthe opposite of natural selection
- 13. Multiple Choice
Yellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.
Genetic Drift
Non-random mating
Gene flow
Mutation
- 14. Multiple Choice
What type of selection is depicted in the picture where one phenotype is favored?
stabilizing
directional
disruptive
- 15. Multiple Choice
Microevolution refers to the small changes in an organism while macroevolution refers to the cumulative changes in an organism that lead to speciation.
True
False
- 16. Multiple Choice
Genetic drift results in reduced genetic variation.
True
False
- 17. Multiple Choice
When comparing populations, the population with the highest amount of genetic diversity is less likely to survive.
True
False
