You decide that. All you have to do is define them before you start. The dominant gene is denoted by a capital letter, the recessive one by a lower case letter. It is better to pick a letter which has different forms for the capital and lower case letters (like A and a; not S and s).

If it's not a heterozygous, the alleles would either be two capital letters (TT) or two lowercase letters (tt). This is because the organism has either both two dominant alleles or two recessive alleles.


What are the letters for homozygous dominant heterozygous and homozygous recessive?

What are the letters for heterozygous?

Actually, there aren't specific letters. The letters depend on the alleles. For example, if the alleles are A and a, then Aa would be heterozygous, since hetero means different. Homozygous, however, would be two of the same alleles, since homo means same. The homozygous would be AA or AA in this example. hope this helped!

What do the letters outside the punnett square stand for a gene?

The letters on the outside of the Punnett square stand for the alleles of each parent. One parent's alleles are written across the top of the square, and the other parent's alleles are written along the left side of the square. The pairs of alleles inside the square represent all the possible genotypes for their offspring.
