I you have seventh grade life science, the answer would be TT and tt ... At least that's what I believe is the answer. Hope I helped!

A Punnett square is used to lay out the possible genotypes of offspring based on the genotypes of the parents being bred. From this, the probabilities of certain phenotypes and genotypes can be determined.
Possible alleles in the gametes of the parents
In genetics a type of grid is used to show the gametes of each parent and their possible offspring and also called the checkerboard is used. The Punnet Square is named after Reginald Crundall Punnett an English geneticist.
Punnett square
A representation called the punette square is used to show the allelic outcomes of off-springs. The construction of this square is based on the genotypes of the two parents. Up to three alleles can be tested simultaneously with this tool. First, the genotypes of the parents for a particular trait are noted down and the possible outcomes written down. When all positions in the table are filled, the genotypic and phenotypic ratios can be calculated.

On the outside of the Punnett Square you put the genotype or two alleles of the parents.
Geneticists use the Punnett square to predict the outcome of a particular breeding experiment. They predict the potential genotypes of the offspring of two parents with known genotypes.

Punnett Squares do not directly tell you the percentages of phenotypes and genotypes, it tells you the probability of the expected genotypes. Based on the Punnett Square, you can infer about the genotypic and phenotypic ratios.

A punit square is essentially a method to work out the possible offsprings of a cross. The information is presented in a tabular for better understanding. The square is used as a tool in genetics to calculate the genootypic and phenopypic rations of certain crosses. The alleles of the parents are places on the two sides of the square and by filling in the grid, we find out the possible outcomes of the cross and determine the genotypic and phenoypic ratios
