Correct Answer: C
Solution:
Epistasis is the masking of one gene over the other, i.e., when one gene inhibits the expression of another gene.
Epistasis is of two types - (i) Dominant epistasis : One dominant allele masks the expression of the other dominant allele (A ® B).
(ii) Recessive epistasis: One recessive allele masks the expression of the other dominant allele (a ® B).
