Question

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

Answer 1

its the first one dude

Answer 2

The answer is the first one. For one and three, the "T" from the mother is crossing with a "t" from the father. On two and four, both of their "t"s are crossing and that's why those are both tt. So, your answer is the first one.
