Effectiveness of Individual and Pedigree Selection
Individual selection & pedigree selection are more effective when heritability of trait is-
- High — Correct Answer
- Low
- Medium
- None
Explanation:
Correct Answer: High
Individual selection and Pedigree selection are both most effective when the heritability (h²) of the trait is high. When h² is high, the phenotype is a reliable indicator of the underlying genotype, making direct measurement of the animal (or its ancestors) sufficient.
Selection Method Effectiveness vs. Heritability
| Method | Most Effective When h² is | Reason |
|---|---|---|
| Individual selection / Mass selection | High | Phenotype closely reflects breeding value |
| Pedigree selection | High | Ancestor performance is a reliable predictor |
| Progeny testing | Low | Averages environmental variation across many offspring |
| Family selection | Low | Reduces environmental noise by using group performance |
