Solution

The correct option is D YR, yr
The parents of Mendel’s dihybrid cross were homozygous for both the characters. One parent having the genotype YYRR was crossed with the other parent of genotype yyrr. Hence, 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.

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.
