Codominance

A genetic scenario where two alleles are both expressed equally in the phenotype of the heterozygote, instead of one being dominant over the other.

Epistasis

A genetic interaction where the effect of one gene is modified by one or several other genes, which can mask or suppress the expression of the first gene.
