Match: Genetic Terms and Their Effects
Match the column:
| TABLE-I | TABLE-II |
|---|---|
| 1) Pleiotropy | a) Increase heterozygosity |
| 2) Linkage | b) Increase homozygosity |
| 3) Inbreeding | c) Random mating |
| 4) Out breeding | d) Transient cause of genetic correlation |
| 5) Panmixia | e) Permanent cause of genetic correlation |
- 1-e, 2-d, 3-b, 4-a, 5-c — Correct Answer
- 1-d, 2-e, 3-b, 4-a, 5-c
- 1-e, 2-d, 3-a, 4-b, 5-c
- 1-c, 2-d, 3-b, 4-a, 5-e
Explanation:
Correct Answer: 1-e, 2-d, 3-b, 4-a, 5-c
The correct matches are:
| Term | Match | Explanation |
|---|---|---|
| 1) Pleiotropy | e) Permanent cause of genetic correlation | One gene affecting multiple traits → causes permanent genetic correlation |
| 2) Linkage | d) Transient cause of genetic correlation | Genes physically linked on chromosome — temporary, breaks up over generations |
| 3) Inbreeding | b) Increases homozygosity | Mating of related individuals → increases homozygosity |
| 4) Out-breeding | a) Increases heterozygosity | Mating of unrelated individuals → increases heterozygosity |
| 5) Panmixia | c) Random mating | Panmixia = random mating (HW equilibrium assumption) |
Key Notes
- Inbreeding = genetic assortative mating; Out-breeding = genetic disassortative mating.
- Causes of genetic correlation: Pleiotropy (permanent) and Linkage (temporary/transient).
- Hardy-Weinberg law requires panmixia (random mating) along with no mutation, migration, or selection.
