Hairy stems (H) are dominant in tomato plants. Hairless stems (h) are

present in tomato plants that are homozygous recessive for this trait.

What percent of tomato plant offspring will have hairy stems if a

homozygous hairy plant is crossed with a heterozygous hairy plant?

All of the tomatoes are going to have hairy stems two of them are homozygous for the trait and the others are heterozygous for the trait

Explanation: When you do the dichotomous key and cross the two parents you will come across this answer

a- all cells come from pre-existing cells
