QUESTION
The selection aid preferred when the heritability of the trait is high is?
OPTIONS
(A) Individual selection
(B) Family selection
(C) Sib selection
(D) Progeny testing
ANSWER
(A) Individual selection
EXPLANATION
When heritability is high, an individual's own phenotype is a relatively reliable indicator of its breeding value, making individual selection particularly effective. Family, sib and progeny selection become comparatively more useful when individual records are less informative, such as for low-heritability traits or sex-limited traits.
