Both terms describe inheritance controlled by the interaction of multiple genes at different loci.

Incomplete dominance describes the interaction of two genes at different loci; epistasis describes the interaction of two alleles.

|
|
Incomplete dominance describes the interaction of two alleles on one gene; epistasis describes the interaction of two genes and their respective alleles.

Detailed explanation-1: -What is the most basic distinction between these terms? Incomplete dominance shows the relationship or coordinated effects of two different gene alleles. On the other hand, epitasis describes the relationship between two different genes.
Detailed explanation-2: -Incomplete dominance-Traits in which the heterozygote shows a different phenotype from the homozygous dominant phenotype. Polygenic-Traits in which several genes contribute to the overall phenotype. Epistasis-The interaction of two genes in which one hides the effects of another.
Detailed explanation-3: -In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
Detailed explanation-4: -Dominance is the phenomenon in which the alleles of the same locus interact with each other to produce a phenotype. Epistasis is a type of interaction that occurs between alleles of the different loci. This is the main difference between dominance and epistasis.
