WebExample of Epistasis - Dominant and Recessive Epistasis It is the phenomenon by which one gene does not allow alleles of another locus to express. This is a counterpart of dominance. While dominance is intragenic suppression (e.g., allele'A’ dominant over ‘a’), epistasis is intergenic suppression (e.g., A suppresses B/B).
