Question

A gardener crosses tall true-breeding pea plants with short true-breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self-pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?

Answer 1

1:2:1 if your only talking about 1 gene that being tall and short

Answer 2

Rnick is right - that will be the ratio of different genotypes. It is not entirely clear whether the question asks for the ratio of genotypes or phenotypes...
