When a gene pair at one locus interacts with another gene at another locus, the interaction is called:
Correct answer: D. Epistasis
- A. Dominance
- B. Multiple Alleles
- C. Pleitropy
- D. Epistasis
Explanation
Epistasis is when a gene at one locus alters the phenotypic expression of a gene at a second locus.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.

When a gene suppresses the effect of another gene at another locus the phenomenon is termed as:
A situation in which one gene affects two or more unrelated characters is called:
When an effect caused by a gene or gene pair at one locus interferes with or hides the effect caused by another gene or gene pair at another locus, the phenomenon is called
