Which evaluation method combines an animal's own records, relatives' records, and information from fixed environmental effects to predict its genetic merit?
Correct answer: B. Best linear unbiased prediction
- A. Simple phenotypic ranking
- B. Best linear unbiased prediction
- C. Random mating analysis
- D. Microsatellite exclusion testing
Explanation
Best linear unbiased prediction, or BLUP, uses records from several sources while accounting for systematic environmental effects. Simple phenotypic ranking does not adequately separate genetic merit from environmental influence.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
