Question

In certain plant species, red flower colour is incompletely dominant to white flower colour (the heterozygote is pink) and tall stems are completely dominant to the dwarf stem. If a tall pink plant (TtRr) is crossed with a tall white plant (TTrr), which one of the following types of plants would be produced in the offspring?

A

Tall pink and tall white

Solution

The correct option is A Tall pink and tall white
The cross between tall pink plant (TtRr) with a tall white plant (TTrr) is given below:

Hence, only tall pink and tall white will be produced in the offspring.
