Question

What should be the percentage of each type of plants in F₂ generation produced in dihybrid cross between pea plants with yellow, smooth seeds and green wrinkled seeds?

Answer 1

1. In F₂ generation of dihybrid cross between pea plants with yellow, smooth seeds and green wrinkled seeds, new plants will produce with the following combination. i) Round and yellow ii) Round and green and iii) Wrinkled and green iv) Wrinkled and yellow 

2. They will produce in the ratio of 9 : 3 : 3 : 1 respectively. 

3. So 56 (56.25%) of plants should be with round and yellow seeds. 19 (18.75%) of plants should be with wrinkled and yellow seeds. 19 (18.75 %) of plants should be with round and green seeds and 6% (6. 25%) of plants should be with wrinkled and green seeds.
