Which method estimates the breeding value of a young sire mainly from the performance of his offspring?
Correct answer: D. Progeny testing
- A. Pedigree recording
- B. Mass selection
- C. Phenotypic grading
- D. Progeny testing
Explanation
Progeny testing evaluates a sire by studying the performance of many offspring produced with different dams. It is especially useful for traits that are difficult or impossible to measure directly in the sire.

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.
