Answer 1

Answer:

Monohybrid cross phenotypic and genotypic ratio

Monohybrid cross Dihybrid cross

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
