Solution

The correct option is B
Double heterozygous

In a typical dihybrid cross, the F₁ hybrid is heterozygous for both the characters. Since both the parents are pure homozygous for contrasting traits, the offspring would be heterozygous dominant. YYRR $\times$ yyrr $\to$ YyRr.

yellow round seed and

yellow wrinkled seeds/ Genotype of the plant with yellow round seeds must be _________.

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.
