Gene Flow

What is gene flow?

• The addition or removal of alleles in a population due to individuals entering or leaving one population for another

• A change in allele frequencies when a new population arises from only a few individuals

• A reduction in population caused by natural disasters, disease, hunting, etc.

• A change in the gene pool due to chance

Green rhinocerous beetles are some of the biggest beetles to exist on Earth. A green rhinocerous beetle leaves its group and wonders over to another group that only has red rhinocerous beetles and mates with the red beetles. This is an example of:

• Genetic Drift

• Mutation

• Migration

Gene flow is most likely to occur between populations that are:

• Geographically isolated.

• Genetically identical.

• Physically close and interbreeding.

• Subject to different selection pressures.
