Question

match up the following terms with the correct definition.

genetic drift
bottleneck effect
founder effect

• process in which allele frequencies change by randomness (chance) in a population
• occurs when a small group splits off from the main population to form a colony
• occurs when a population is greatly reduced due to a natural disaster

Explanation:

1. Genetic Drift: Defined as the process where allele frequencies change due to randomness (chance) in a population. So match "Process in which allele frequencies change by randomness (chance) in a population" with Genetic Drift.
2. Bottleneck Effect: Occurs when a population is greatly reduced due to a natural disaster (like an earthquake, flood, etc., that drastically reduces population size). So match "Occurs when a population is greatly reduced due to a natural disaster" with Bottleneck Effect.
3. Founder Effect: Happens when a small group splits off from the main population to form a colony (this new group is the "founders" of a new population). So match "Occurs when a small group splits off from the main population to form a colony" with Founder Effect.

Answer:

• Genetic Drift: Process in which allele frequencies change by randomness (chance) in a population
• Bottleneck Effect: Occurs when a population is greatly reduced due to a natural disaster
• Founder Effect: Occurs when a small group splits off from the main population to form a colony
