The main purpose of a progeny test in dairy cattle is to evaluate a sire by examining the performance of his:
Correct answer: A. Daughters
- A. Daughters
- B. Parents
- C. Siblings
- D. Mating partners
Explanation
A dairy sire is commonly evaluated through the milk production of many daughters because daughters inherit half of their genes from him. The performance of parents or siblings provides different types of family information.

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.
