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

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

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.

• Gene flow

• Natural Selection

• Bottleneck Effect

• Founder Effect.

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.
