Text Solution

Verified by Experts

To determine the genotype of a tall pea plant, a test cross is made in which the tall pea plant with be crossed with a drawf pea plant.

In case 1. the plant is heterozygous tall and the F ratio between tall and dwarf plants will be 1 : 1. In case 2. the tall plant is homozygous tall and all the offspring will be tall.
