WebApr 4, 2024 · The phenomena of duplicate dominant epistasis or duplicate gene action involve a dominant allele (it is an alternative form of a gene) that masks the expression of recessive alleles at two loci (it is a position on a chromosome where a gene is located). Due to this, the same type of phenotypic effect is produced and the ratio becomes 15:1.
