Question

Rounded seeds (dominant trait ) were crossed with wrinkled seeds . (i) what type of seds will be produced in F1 generation . (ii) by self pollination in F1 seeds , what percentage of seeds will be rounded shape in F2 generation . Explain with diagram .

Answer 1

*Here is your answer*

(i) Rounded seeds

As RR (rounded) and rr(wrinkled) are crossed the seeds would be Rr, Rr, Rr, Rr which all would be rounded.

(ii) 75%

After self pollination in F1 hybrid, the seeds would be RR, Rr, Rr, rr. 3/4 would be rounded so the percentage would come as 75%.
