In case of recessive epistasis
WebRecessive alleles of two different genes may give the same phenotype. Epistasis. The alleles of one gene may mask or conceal the alleles of another gene. In addition, some gene pairs lie near one another on a chromosome and are genetically linked, meaning that they don’t assort independently.

Therefore epistasis may be responsible for the production of several modified dihybrid ratios as follows: Duplicate recessive epistasis (9:7) Dominant epistasis (12:3:1) Recessive epistasis (9:3:4) Dominant recessive epistasis (13:3)
WebFinally, epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same phenotype.
