Q.Gene which suppresses other gene's activity but does not lie on the same locus is called as

Epistasis is an intergenic (non-allelic) gene interaction in which the alleles of one gene at one locus interfere with, suppress, or mask the phenotypic expression of a different gene's alleles at another locus. The gene doing the masking is called epistatic; the gene whose expression is blocked is called hypostatic - when both genes are present together in an individual, the phenotype is determined by the epistatic gene, and the hypostatic gene's own character does not show at all. Epistasis characteristically reshapes the standard 9:3:3:1 dihybrid F2 ratio into one of several other named, diagnostic ratios depending on exactly how the two loci interact: dominant epistasis (12:3:1, fruit colour in summer squash), recessive epistasis (9:3:4, flow …
