Solution

The correct option is A
Round yellow seeds

Yellow colour of pea seeds is dominant over green color and round shape of pea seeds is dominant over wrinkled ones.

A cross between pure yellow round seeded plants (YYRR) and green wrinkled seeded plants (yyrr) would yield heterozygous plants with yellow round seeds (YyRr) in the $F_{1}$ generation.

Q. A person first crossed pure-bred pea plants having round-yellow seeds with pure-bred pea plants having wrinkled-green seeds and found that only A-B type of seeds were produced in the

F_{1}

generation. When

F_{1}

generation pea plants having A-B type of seeds were cross-bred by self-pollination, then in addition to the original round-yellow and wrinkled-green seeds, two new varieties A-D and C-B type of seeds were also obtained.

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 $F_{1}$ generation. When $F_{1}$ 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?
