Both RR and Rr genotypes result in the same phenotype because the dominant allele ® masks the recessive allele ®, so both display the dominant trait.

Beyond the Answer
Both genotypes, RR and Rr, lead to the same phenotype because they both produce the dominant allele R. In genetics, the dominant allele ® can mask the expression of the recessive allele ®. Since RR has two copies of the dominant allele, while Rr has one dominant and one recessive allele, they both manifest the same observable traits, or phenotype. So, whether an organism is homozygous dominant (RR) or heterozygous (Rr), they’ll both display the characteristics associated with the dominant trait.
This principle mirrors the idea of a team wearing identical jerseys. If two players wear the same dominant color, like red, whether one player has a light version of that jersey or a dark version doesn’t change the fact that they both look like part of the same team! It’s all about appearance here.
