Solution

Monohybrid cross Dihybrid cross
This involves a cross between two organisms of pure line to study the inheritance of a single allelic pair. This involves a cross between two organisms of pure line to study the inheritance of two pairs of alleles having different characters.
The phenotypic ratio in F2 generation is 3:1 The phenotypic ratio in F2 generation is 9:3:3:1
The genotypic ratio in F2 generation is 1:2:1 The genotypic ratio in F2 generation is
1:2:1:2:4:2:1:2:1
The test cross ratio is 1:1 The test cross ratio is 1:1:1:1
