Match the following with respect to Mendel’s inheritance of one gene experiments.
List – I List – II
A) P generation I) All tall or tall and dwarf in 1:1 ratio
B) $F_{1}$ generation II) Heterozygous tall are double the number of homozygous tall plants.
C) $F_{2}$ generation III) Only true breeding lines
D) Test cross progeny IV) Only heterozygous plants

List – I	List – II
A)	P generation	I)	All tall or tall and dwarf in 1:1 ratio
B)	$F_{1}$ generation	II)	Heterozygous tall are double the number of homozygous tall plants.
C)	$F_{2}$ generation	III)	Only true breeding lines
D)	Test cross progeny	IV)	Only heterozygous plants

Solution

P generation is parental generation which has true breeding plants differed with respect to single character. $F_{1}$ is first filial generation obtained upon the cross between true breeding parents. It produced heterozygous plants with expression of dominant traits. $F_{2}$ generation is the offspring obtained upon selfing or intercrossing in $F_{1}$ individuals. It had a genotypic ratio of 1:2:1 with heterozygous tall plants double the number of homozygous tall. When tall plants of $F_{2}$ generation are test crossed by crossing with recessive parents he obtained either all tall plants if it is homozygous tall or obtained tall and dwarf plants in 1:1 ratio if the tall plant is heterozygous.
