Solution

The correct option is B Epistasis
Epistasis occurs when two or more different gene loci contribute to the same phenotype, but not additively. Epistasis is often described as occurring when one gene locus masks or modifies the phenotype of a second gene locus. The epistatic gene pair is present on non-homologous chromosomes, an interaction that is termed as non-allelic.
So, the correct answer is option A.
