Question

A tall pea plant (TT) is crossbred with a short pea plant (tt). The Punnett square below 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

Answer 1

Hi there!

Using the image below, you can see that all of the boxes are Tt, or heterozygous. Therefore, 1 = Tt, 2 = Tt, 3 = Tt, and 4 = Tt.

Hope this helps!! :)
