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?

A pea plant with pure Yellow (YY) Round (RR) seeds was crossed with a plant having pure green (yy) wrinkled (rr) seeds. What would be the nature of offspring in the F1- generation?
