QUESTION
Which of following genetic parameter can be used to predict future performance of the same individual?
OPTIONS
(A) Heritability estimate (broad sense)
(B) Repeatability estimate
(C) Heritability estimate (narrow sense)
(D) Non-additive genetic variance
ANSWER
(B) Repeatability estimate
EXPLANATION
Repeatability estimates the proportion of phenotypic variance attributable to permanent differences among individuals, including permanent genetic and permanent environmental effects, and is useful for predicting future performance of the same individual from previous records. Heritability specifically concerns genetic variance and is not as directly suited to predicting an individual's future repeated record.
