To classify the combinations of alleles:

Homozygous Dominant: This means that both alleles are the same and both are dominant. The combination would be TT.
Homozygous Recessive: This means that both alleles are the same and both are recessive. The combination would be tt.
Heterozygous: This means that the two alleles are different, with one being dominant and the other recessive. The combination would be Tt.

In summary:

Homozygous Dominant: TT
Homozygous Recessive: tt
Heterozygous: Tt
