Question

A farmer mates a homozygous tall, red tomato plant (TTRR) with a
heterozygous tall, red tomato plant (TtRr). What is the percent chance that the
offspring will be dwarf plants with yellow
fruit?
(Remember: In tomatoes, tall vines (T) are dominant to dwarf vines (t), and red
fruit (R) is dominant to yellow fruit (r))

Answer 1

Answer:

I think there is 50% chance

Answer 2

Answer:

The resulting gametes from RrTT plant will be RT and rT and the gametes from rrTt plant will be rT and rt. Now, RrTT X rrTt plant will result in genotypes as shown. So, only one will be heterozygous for both traits and therefore the probability will be 1/4. So, the correct option is '1/4'.
