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.
Punnett square showing female parent across the top with a phenotype of tall and a genotype of TT and a male parent across the side with a phenotype of short and a genotype of tt. Inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written.
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
1 = TT; 2 = Tt; 3 = Tt; 4 = Tt
1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt
