Match the following lists: List - I List - II (A) Back cross It is the genetic make up of an individual. (B) Test cross (II) An individual is having two different alleles for a single character. Consequently, it will produce two different types of gametes with reference to a gene. (C) Heterozygote (III) An individual is having two similar or identical alleles for a single character. Hence, it will produce only one kind of gametes with reference to a gene. (D) Homozygote (IV) If the F 1 progeny are mated back to one of their parents. (V) The cross between F 1 progeny (or heterozygotes) and their recessive homozygous parent. The correct match is:

A = IV , B = V , C = II , D = III

A = IV , B = V , C = I , D = II

A = V , B = III , C = I , D = II

A = V , B = IV , C = II , D = I

Phenotype is defined as the external appearance of an individual for any trait. It is observable and is determined by different combinations of alleles. For example, in the pea plant, the coloured flower represented by the genotype CC and Cc and the white flower represented by the genotype cc are the two phenotypes.

Match the following lists:

	List - I		List - II
(A)	Back cross		It is the genetic make up of an individual.
(B)	Test cross	(II)	An individual is having two different alleles for a single character. Consequently, it will produce two different types of gametes with reference to a gene.
(C)	Heterozygote	(III)	An individual is having two similar or identical alleles for a single character. Hence, it will produce only one kind of gametes with reference to a gene.
(D)	Homozygote	(IV)	If the $F_{1}$ progeny are mated back to one of their parents.
		(V)	The cross between $F_{1}$ progeny (or heterozygotes) and their recessive homozygous parent.
