Solution
(c) Epistasis is the masking of one gene over the other i.e., when one gene inhibits other gene to express. Epistasis is of two types –
$(i)$ Dominant epistasis : One dominant allele masks the other dominant allele $(A → B)$.
$(ii)$ Recessive epistasis : One recessive allele masks the other dominant allele $(a → B)$.
