Which measure is most directly used to express the genetic merit of an animal for selection purposes?
Correct answer: D. Estimated breeding value
- A. Generation interval
- B. Phenotypic record
- C. Selection differential
- D. Estimated breeding value
Explanation
Estimated breeding value predicts the additive genetic merit that an animal can transmit to its offspring. A phenotypic record also contains environmental effects, while selection differential and generation interval describe selection or breeding processes.

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.
