A scientist has decided to repeat Mendel’s experiment on pea plants by crossing a short pea plant (tt) with tall pea plant (TT). Which of the following would be the outcome of this experiment?

A 100 percent of the offspring will be tall.

100 percent will be tall because one parent plant gave a T and the other gave a t. Each parent will give one gene to the baby, and because the tall plant had two TT, it only could give a T. Likewise, the short plant only had one t to give. A plant with Tt will be tall because the T (tall) is dominant.
