In a genetic experiment, plants with pure round green seeds (RRyy) were crossed with plants with wrinkled yellow seeds (rrYY). (i) Show the gametes formed when F1 was self-pollinated. (ii) A total of 144 seeds were produced which developed into saplings. Show the ratio in which these traits are independently inherited in these 144 saplings.

Cross: RRyy × rrYY → F₁: RrYy (round yellow). On self-pollination, F₂ shows 9:3:3:1 ratio (round yellow : round green : wrinkled yellow : wrinkled green) due to independent assortment of genes. cbse sample paper 2026 cbse sample paper 2025-26 class 10
