WebRecessive Epistasis Epistasis (which means “standing upon”) occurs when the phenotype of one locus masks, or prevents, the phenotypic expression of another locus. Thus, following … WebThe recessive trait will only be expressed by offspring that have two copies of this allele ( Figure ), and these offspring will breed true when self-crossed. Since Mendel’s experiments with pea plants, researchers have found that the …

The presence of recessive alleles at one locus makes useless the presence of dominant alleles at another locus. This happens if two enzymes are needed in series; "the chain breaks" if either link fails. The Mendelian ratio of a dihybrid cross is 9:7.
