So either both of those alleles are actually dominant or both of those alleles are actually recessive. In the case that they're both dominant, this is known as homozygous dominant. In the case they're both recessive, that is known as homozygous recessive. So this is the genotype of the homozygous dominant and this is the genotype of the homozygous recessive. Now, what is the phenotype in this case? Well, because we have two of these genes both of these genes code for proteins that express the tall height this will be a tall individual or a tall plant and that will be the phenotype the physical appearance, on the other hand, lowercase T's because we don't have any dominant trait both of these traits are recessive.
