Force That Changes Gene Frequency Fastest
Which force changes the gene frequency the fastest?
- Migration
- Genetic drift
- Mutation
- Selection — Correct Answer
Explanation:
Correct Answer: Selection
Selection is the force that changes gene frequency the fastest. It is also the process that increases the frequency of desirable genes without introducing new genes.
Speed of Gene Frequency Change by Force
| Force | Speed of Change | Notes |
|---|---|---|
| Selection | Fastest | Directional, most powerful; used in animal breeding |
| Migration | Intermediate | Predictable in amount and direction |
| Genetic drift | Variable | In small populations; unpredictable in direction |
| Mutation | Slowest | Mutation rate is very low; ultimate source of new alleles |
