QUESTION
Which basis of selection cannot be used for selection of sire for milk production?
OPTIONS
(A) Performance of collateral relatives
(B) Performance of ancestor
(C) Performance of progeny
(D) Performance of individual
ANSWER
(D) Performance of individual
EXPLANATION
An individual's own milk-production performance cannot be used to select a sire directly because milk production is a sex-limited trait and males do not express the phenotype. Ancestor, collateral-relative and progeny records can provide information about a sire's genetic merit for milk production.
