Question
Distinguish between the following:
Gene flow and Genetic drift.
Gene flow and Genetic drift.
✓
Answer
| Gene flow | Genetic drift |
| 1. Gene flow is the alteration in the gene frequency due to migrations. | 1. Genetic drift is alteration in the gene frequency by pure chance. |
| 2. Gene flow occurs due to exchange of genes in the adjacent populations through interbreeding. | 2. Genetic drift occurs due to accidental and sudden elimination of a particular gene. |
| 3. Larger populations tend to show more migrations and hence more gene flow. | 3. Smaller populations have greater chances of genetic drift. |
| 4. Gene flow occurs due to emigration and immigration. | 4. Genetic drift occurs only within the specified population. |
