Vedclass · Answer

(A) When one gene masks the effect or activity of another gene which does not lie on the same locus,it is called epistasis. The gene that suppresses the other is known as the epistatic gene,while the gene whose expression is masked is called the hypostatic gene. Epistasis refers to non-allelic interactions. For example,coat colour in mice is controlled by an epistatic gene. When a coloured $(CCaa)$ mouse is crossed with an albino $(ccAA)$ mouse,agouti mice $(CcAa)$ appear in the $F_1$ generation. In the $F_2$ generation,agouti,coloured,and albino mice are obtained in a $9:3:4$ ratio.
