Basis of Estimation via Resemblance Between Relatives
'Resemblance between relatives' is the basis of estimation of:
- Repeatability only
- Genetic Correlation only
- Heritability only
- Both Heritability and Genetic Correlation — Correct Answer
Explanation:
Correct Answer: Both Heritability and Genetic Correlation
Resemblance between relatives is the basis of estimation of both Heritability and Genetic Correlation.
Covariance of Relatives
| Relatives | Covariance | Heritability Formula |
|---|---|---|
| Offspring and one parent | ½ VA | h² = 2b |
| Offspring and mid parent | ½ VA | h² = b |
| Half sibs | ¼ VA | h² = 4t |
| Full sibs | ½ VA + ¼ VD + VEC | h² = 2t |
Note: Best method of heritability estimation (relatively free from biases) = Half-sib correlation method. Least reliable = Full-sib correlation.
