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

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

The correct match is 1 = Tt; 2 = tt; 3 = Tt; 4 = tt

What is a Punnet Square?

A punnet square allows us to see the different genotypes and phenotypes of the offspring.

  • Phenotype is the physical characteristics that we can see from a gene, like height.
  • Genotype is the genetic information that something carries. We can not see it. For example, we know that a pea can carry a gene for height and another for shortness, but we cannot see it.

The Punnet Square

According to the information that we have, the Punnet Square will look as follows:

TT x tt

 ║T ║t

t ║Tt║tt

t ║Tt║tt

We can see that the genotypes are:

  • The top left box (1) is Tt
  • The top right box (2) is Tt
  • The bottom left box (3) is Tt
  • The bottom right box (4) is tt
