The correct option is D
YR & yr

The parents in Mendel’s dihybrid cross were pure lines and were homozygous for both the characters.

So, parent with genotype (YYRR) was crossed with the parent of genotype (yyrr).

They produced two type of gametes, (YR) from the homozygous parent with the dominant trait and (yr) from the homozygous parent with the recessive trait.

Q. A cross between parent pea plants having green round seeds with those having yellow wrinkled seeds would produce

F_{1}

plants with ____.

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?
