What do the letters inside of the squares represent?

The letters on the outside of a Punnett square represent the alleles of the parents that are involved in a genetic cross. Each parent has two alleles for a trait (one inherited from each parent), and these alleles are typically represented by letters, with capital letters denoting dominant alleles and lowercase letters representing recessive alleles.
For example, if you are considering a trait determined by a single gene with two alleles (e.g., T for tall and t for short), you might see the following:
- Parent 1 could be homozygous dominant (TT) or heterozygous (Tt), and you would write that on the top of the Punnett square.
- Parent 2 could similarly be either TT or Tt, and you would write that along the side of the square.
The combinations of these alleles inside the squares are used to predict the possible genotypes of offspring resulting from the cross.
