Basis of Selection That Cannot Be Used for Sire for Milk Production
Which basis of selection cannot be used for selection of a sire (male) for milk production?
- Performance of collateral relatives
- Performance of individual — Correct Answer
- Performance of ancestors
- Performance of progeny
Explanation:
Correct Answer: Performance of individual
Individual selection (based on performance of the individual itself) cannot be used for selecting a sire for milk production because milk production is a sex-limited trait — a bull (sire) cannot produce milk, so its own performance cannot be measured.
