WebMar 27, 2024 · Epistasis Definition Epistasis is the interaction between genes that influences a phenotype. Genes can either mask each other so that one is considered “dominant” or they can combine to produce a new … WebThe normal ratio from selfing dihybrid is 9:3:3:1, but epistatic interactions of the C and P genes will give a modified 9:7 ratio. The following table describes the interactions for each genotype and how the ratio occurs. Because both genes are required for the correct phenotype, this epistatic interaction is called complementary gene action .
