Natural Selection and Population Genetics Quiz Review

What is Gene Flow?

• The process of natural selection in a population.

• The movement of genes from one population to another.

• The transfer of energy between organisms in an ecosystem.

• The change in allele frequency due to random sampling.

What is a Population?

• A group of the same species, living together in a specific area.

• A collection of different species in a habitat.

• An individual organism of a species.

• A random assortment of organisms in an ecosystem.

Match the term: Organisms with traits well suited to their environment survive and reproduce more successfully than organisms less suited to the same environment.

• Natural Selection

• Evolution

• Genetic Drift

• Adaptation

What are Mutations?

• A change in DNA causing an advantage for an organism to develop a new trait.

• A process that eliminates harmful traits from a population.

• A method of DNA replication that ensures genetic stability.

• A type of genetic engineering used to create new species.

What is Genetic Drift?

• A process that leads to the extinction of species.

• Random change in the alleles in a population.

• A method of artificial selection in breeding.

• A type of genetic mutation that occurs frequently.

What are the 4 Principles of Natural Selection?

• Variation of traits, competition to survive, overproduction of offspring, and survival of the fittest.

• Adaptation to environment, genetic drift, natural selection, and mutation.

• Survival of the fittest, environmental stability, limited resources, and genetic variation.

• Overproduction of offspring, competition for resources, environmental change, and extinction.

What is Variation?

• It increases an organism's chance of survival.

• It decreases genetic diversity.

• It has no effect on survival.

• It is a method of reproduction.
