A cross between pure-bred pea plants having yellow round seeds with those having green wrinkled seeds would produce F1 plants with:
Round yellow seeds
Round green seeds
Wrinkled yellow seeds
Wrinkled green seeds
Mendel first crossed pure-bred pea plants having round -yellow seeds with pure-bred pea plants having wrinkled -green seeds and found that only round- yellow seeds were produced in the F1 generation. When F1 generation pea plants having round-yellow seeds were cross-bred by self-pollination, then peas having round-yellow seeds, round green seeds, wrinkled-yellow seeds and wrinkled -green seeds were produced. Mendel collected a total of 2160 seeds.
(a) What will be the number of (i) round green seeds (ii) wrinkled green seeds (iii) round yellow seeds, and (iv) wrinkled-yellow seeds?
(b) Which 'ratio' as established by Mendel have you made use of in answering the part (a) above?
A pea plant with round and yellow seeds (RRYY) is crossbred with another pea plant having wrinkled and green seeds (rryy). Among the offspring obtained in F2 generation, plants with which traits were found to be maximum in number?
