Solution

The correct option is D 1
A plant with short-wrinkled seeds on self-crossing will give rise to plants all of which have short wrinkled seeds. This is a dihybrid cross. The genotype of the parents will be ttrr. On crossing, all the progeny plants will have the genotype ttrrr and will be short with wrinkled seeds. So only one kind of plant will be produced. Thus the correct answer is option D.

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.
