Epistasis is the gene in which
a gene ( epistatic gene) can disallow
phenotypical manifestation of
another (the hypostaticgene). In
dominant the inhibitor allele is
dominant allele (for example, )of
the epistatic gene so occurs in
dominant homozygosity () or in
heterozygosity (Ii). recessive
epistasis the inhibitor isthe
recessive allele of epistatic gene (i)
so occurs only in recessive
(ii).
