How to make monohybrid cross for class 10 board examination...

Monohybrid cross is the cross that involves only a single character.
Let us take the example of cross between the two homozygous plants considering a single character height with genotype TT and tt. The cross can be illustrated as:

Phenotype ratio in F2 generation = 3 : 1 i.e 3 tall and 1 dwarf
Genotype ratio in F2 generation = 1 : 2 : 1 i.e 1 TT, 2 Tt and 1 tt.

Hope this helps.
Regards.
