	Column I		Column II
(1)	Dominance	(i)	Many genes govern a single character
(2)	Codominance	(ii)	In a heterozygous organism only one allele expresses itself
(3)	Pleiotropy	(iii)	In a heterozygous organism both alleles express themselves fully
(4)	Polygenic inheritence	(iv)	A single genes influences many characters

• A. 1- ii, 2 - i, 3 - iv, 4 - iii
• B. 1 - ii, 2 - iii, 3 - iv, 4 - i
• C. 1 - iv, 2 - i, 3 - ii, 4 - iii
• D. 1- iv, 2 - iii, 3 - i, 4 - ii

Answer 1

The correct option is B 1 - ii, 2 - iii, 3 - iv, 4 - i

Dominance – In a heterozygous organism only one allele expresses itself.
Codominance – In a heterozygous organism both alleles express themselves equally.
Pleiotropy – A single gene influences many characters.
Polygenic Inheritance – Many genes govern a single character.
