Progeny testing is used to select-
- Parent — Correct Answer
- Progeny
- Full sib
- None
Explanation:
Correct Answer: Parent
The primary purpose of progeny testing is to evaluate and select the parent — most often the sire. The offspring's performance is merely the measurement instrument used to judge the parent's true breeding value.
Progeny Testing — Key Facts
- Most effective and best basis of selection overall
- Most accurate for evaluating sires for sex-limited traits (e.g., milk yield, egg production)
- Described as a 'two-way selection system' — identifies superior sires AND culls inferior ones
- More daughters tested → more accurate estimate of sire's Breeding Value
- Generation interval is longest among all selection bases
Comparison — Target of Selection
| Basis of Selection | Evaluated Based on | Target of Selection |
|---|---|---|
| Progeny testing | Offspring performance | Parent (sire) |
| Individual selection | Own phenotype | The individual itself |
| Pedigree selection | Ancestor performance | The individual (predicted from ancestors) |
| Family / Sib selection | Sibling performance | The individual (predicted from sibs) |
