Definition:

When the phenotypic effect of alleles at one gene are masked by alleles of another gene.

In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.

It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.

  • Dominant

  • Dominant inhibitory,

  • Duplicate dominant,

  • Duplicate recessive,
