Force That Changes Gene Frequency Slowest
Which force changes gene frequency the slowest?
- Mutation — Correct Answer
- Migration
- Selection
- Random drift
Explanation:
Correct Answer: Mutation
Mutation changes gene frequency the slowest because the natural mutation rate is extremely low (typically 10⁻⁵ to 10⁻⁶ per gene per generation).
Speed Comparison of Forces
- Fastest: Selection
- Intermediate: Migration, Genetic drift
- Slowest: Mutation
Despite being the slowest, mutation is the ultimate source of all new alleles and new genetic variation in a population. Without mutation, there would be no new raw material for evolution or selection to act upon.
