DOMINANT EPISTASIS
In dominant epistasis, however, only a single copy of an allele is required to inhibit the expression of an allele at a different locus.

DUPLICATE RECESSIVE EPISTASIS(9:7): Duplicate recessive epistasis, in which two recessive alleles at either of two different loci can suppress a phenotype.
