| 2) Progeny testing | b) Best aid to selection for carcass traits in sheep |
| 3) Individual selection | c) Most efficient aid to selection |
| 4) Sib selection | d) Most efficient method of selection |
- 1-d, 2-a, 3-c, 4-b
- 1-c, 2-b, 3-a, 4-d
- 1-d, 2-c, 3-a, 4-b — Correct Answer
- 1-b, 2-c, 3-d, 4-a
Explanation:
Correct Answer: 1-d, 2-c, 3-a, 4-b
Correct Matching
| Aid/Method | Match | Explanation |
|---|---|---|
| Selection Index (1-d) | Most efficient method of selection | Best method among multi-trait selection methods; gives single numerical score with economic weights for all traits |
| Progeny testing (2-c) | Most efficient/accurate aid to selection | Most effective and best basis; two-way selection system; used for sex-limited and low-h² traits; used for sire selection |
| Individual selection (3-a) | Most accurate aid to selection | Most accurate when h² is high; simplest, most rapid; based on animal's own phenotype |
| Sib selection (4-b) | Best aid for carcass traits (slaughter traits) | When the animal must be slaughtered to evaluate, siblings are slaughtered and their genetic merit inferred for surviving sibs |
Summary — Basis of Selection
- Sire selection: Progeny testing
- Carcass/slaughter traits: Sib selection
- High-h² traits: Individual selection
- Multi-trait simultaneously: Selection index
