प्रश्न
Two pea plants - one with round yellow seeds (RRYY) and another with wrinkled green (rryy) seeds produce F1 progeny that have round, yellow (RrYy) seeds.
When F1 plants are self-pollinated, which new combination of characters is expected in F2 progeny? How many seeds with these new combinations of characters will be produced when a total 160 seeds are produced in F2 generation? Explain with reason.

उत्तर
Round green : 30
Wrinkled yellow : 30
New combinations are produced because of the independent inheritance of seed shape and seed colour trait.
