In complementary gene action, both the non allelic pair independently produce similar phenotypes and when present together produce a new phenotype. So, that F2 ratio 9: 3: 3: 1 would become 9: 7.

Epistasis is the suppression of the normal phenotypic expression of the gene by a non-allelic gene. Complimentary genes are two independent genes present on different gene loci which assist each other in expressing a trait. Supplementary genes are two independent genes present on different gene loci, each of which may produce its own trait and interact when present together in dominant state to produce a new trait.

According to principle of dominance, out of the two factors of alleles representing different traits of a character, only one expresses itself. But when both express themselves it is codominance.
