- 1. Multiple Choice
This term refers to the total genetic information found in a population; the complete collection of all the alleles found in a population
Gene library
Genome
Gene pool
Allele pool
- 2. Multiple Choice
This is one of the mechanisms of evolution; it occurs when individuals move into or out of a population, either by physically arriving or leaving, or by being born or dying
Gene flow / genetic drift
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 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
- 5. 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
- 6. Multiple Choice
Today, the Afrikaner population has an unusually high frequency of the gene that causes Huntington's Disease, because the Dutch colonists happened to carry that gene with unusually high frequency.

Thanks to a better food source, giraffes with longer necks were able to survive to reproduce and so passed on the characteristic to the succeeding generation.

- 14. Multiple Choice
Northern elephant seals have reduced genetic variation because of humans hunting them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century.
Gene flow

bottleneck effect
founder effect.
- 15. Multiple Choice
Which of the following statements about gene flow is TRUE?
Gene flow is a result of individuals that breed in an old location
Gene flow is a result of migrating individuals that breed in a new location
Gene flow is not a result of migrating individuals that breed in a new location
None of the statements are true
- 16. Multiple Choice
How do evolution directly affected by the gene flow?
It doesn’t contribute to evolution
It introduces new alleles into a population.
It reduces the number of members in a population.
It changes the environment in which a population resides.
- 17. Multiple Choice
In order for the genetic drift to occur, what is the necessary parameter?
The population must be large.
The population must be small.
The population must be under environmental stress.
The population must be sterile.
- 18. Multiple Choice
What will happen to the organisms during natural selection?
Organisms tend to remain the same
Organisms tend to adapt the changes
Organisms tend to ignore the changes
None of the statement is correct
- 19. Multiple Choice
What should fittest individual must do in order for the evolution to occur?
Avoid predators more successfully
Be better at obtaining food
Leave more offspring
Must be sterile
- 20. Multiple Choice
In what situation, artificial selection takes place?
Susceptibility testing of microorganisms against antibiotics
The different finches found by Darwin in the Galapagos
Cultivations of new varieties of rice plants
Elongated neck of giraffe
