Factors Affecting Gene Frequency Due to Migration

Question

Change in gene frequency due to migration will depend upon:

Select an answer

Change in gene frequency due to migration will depend upon:

  1. Gene frequency of migrants
  2. Proportion of migrants
  3. Gene frequency of base population
  4. 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
