The accuracy of an estimated breeding value is the correlation between the estimated breeding value and the:
Correct answer: D. True breeding value
- A. Animal's phenotypic record
- B. Genotypic value of its offspring only
- C. Environmental deviation
- D. True breeding value
Explanation
Accuracy measures how closely an estimated breeding value reflects the animal's true additive genetic merit. A phenotype may contribute to the estimate, but it is not the reference quantity used to define accuracy.

About Animal Breeding and Genetics
Covers genes, chromosomes, inheritance, genetic variation, mutations, heritability and quantitative traits in livestock. It also includes selection methods, breeding systems, inbreeding, crossbreeding, heterosis and evaluation of traits such as growth, milk yield, fertility and disease resistance.
