A gene interaction occurs when the effect of one gene masks or modifies the expression of another gene at a different locus. This interaction is called:
Correct answer: D. Epistasis
- A. Incomplete dominance
- B. Pleiotropy
- C. Linkage
- D. Epistasis
Explanation
Epistasis is interaction between genes at different loci, where one locus affects the expression of another. Pleiotropy instead refers to one gene influencing several traits.

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.
