Question 1

1 / -0

Match the column I and II.

	Column-I		Column-II
(a)	Pleiotropic gene	(i)	Both allele express equally
(b)	Co-dominance	(ii)	Change in nucleotide
(c)	Epistasis	(iii)	One gene shows multiple phenotypic expression
(d)	Mutation	(iv)	Non-allelic gene inheritance

(a)-i, (b)-ii, (c)-iii, (d)-iv

(a)-ii, (b)-iii, (c)-iv, (d)-i

(a)-iii, (b)-i, (c)-iv, (d)-ii

(a)-i, (b)-iii, (c)-iv, (d)-ii

Solution

Pleiotropic gene - Pleiotropy occurs when one gene when one gene influences two or more seemingly unrelated phenotypic traits.
Co-dominance - Co dominance occurs when two versions of the same gene are present in the same living thing and both are expressed.
Epistasis - Epistasis is the phenomenon in which the effect of one gene is dependant on the presence of one or more modifier genes.
Mutation - Mutation is the alteration of the nucleotide sequence of and organism.

So the correct option is C.
