Factors Affecting Gene Frequency Due to Migration
Change in gene frequency due to migration will depend upon:
- Gene frequency of migrants
- Proportion of migrants
- Gene frequency of base population
- All the above — Correct Answer
Explanation:
Correct Answer: All the above
Migration (gene flow) changes gene frequencies in the recipient population. The magnitude of this change depends on all three factors listed.
Formula for Change in Gene Frequency due to Migration
Δq = m(qm − q₀)
- m = Proportion of migrants entering the population
- qm = Gene frequency of the migrating group
- q₀ = Original gene frequency of the base (recipient) population
Forces Affecting H-W Equilibrium
| Force | Type | Acts on | Speed of Change |
|---|---|---|---|
| Mutation | Systemic | All populations | Slowest |
| Migration | Systemic | All populations | Moderate |
| Selection | Systemic | All populations | Fastest |
| Random Genetic Drift | Dispersive | Small populations only | Unpredictable |
