Population Evolution

What increases genetic variation when animals move from one population to another

• genetic drift

• sexual selection

• bottleneck effect

• gene flow

This mechanism of evolution occurs when populations migrate.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

A change in a gene due to damage or incorrect copying is called

• evolution

• meiosis

• segregation

• a mutation
