Cause of Transient Genetic Correlation
Transient genetic correlation between two traits is due to-
- Linkage — Correct Answer
- Pleiotropy
- Both
- None
Explanation:
Correct Answer: Linkage
Linkage is the transient (temporary) cause of genetic correlation. When genes controlling two different traits are located close together on the same chromosome, they are inherited together, creating a correlation. However, crossing over can break this association over generations, making it temporary.
Causes of Genetic Correlation — Summary
| Cause | Type of Correlation | Reason |
|---|---|---|
| Pleiotropy | Permanent | One gene affects multiple traits — cannot be separated |
| Linkage | Transient / Temporary | Genes on same chromosome — can be broken by recombination |
| Heterozygosity | Variable | Also listed as a cause of genetic correlation |
Example of permanent correlation (pleiotropy): Sickle cell anemia gene affects multiple traits simultaneously.
