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.

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.
