A tall pea plant (TT) is crossbred with a short pea plant (tt). The following Punnett square shows the separated alleles for two pea plants. Which of the following shows the correct match of the box numbers and the genotype of the offspring?
1 = TT; 2 = TT; 3 = Tt; 4 = Tt
1 = TT; 2 = Tt; 3 = Tt; 4 = tt
