Column-I		Column -II
(a)	Dominance	(i)	Many genes govern a single character
(b)	Codominance	(ii)	In a heterozygous organism only one allele expresses itself
(c)	Pleiotropy	(iii)	In a heterozygous organism both alleles express themselves fully
(d)	Polygenic inheritance	(iv)	A single gene influences many characters

• A. $(a)\rightarrow (ii) , (b) \rightarrow (iii) , (c) \rightarrow (iv) , (d) \rightarrow (i)$
• B. $(a)\rightarrow (iv) , (b) \rightarrow(i) , (c) \rightarrow (ii) , (d) \rightarrow(iii)$
• C. $(a) \rightarrow (iv) , (b) \rightarrow (iii) , (c) \rightarrow (i) , (d) \rightarrow (ii)$
• D. $(a) \rightarrow (ii) , (b) \rightarrow (i) , (c) \rightarrow (iv) , (d) \rightarrow (iii)$
