Having a dimpled cheek is a dominant trait (d) and having a non-dimpled cheek is a recessive trait (d). if someone is homozygous dominant, then what genotype does the person carry?

The genes of an organism can be either a homozygous or a heterozygous one. When someone is a homozygous dominant, it means that it has two copies of the same dominant allele. Homozygous means that the organism has exact copies of the same gene allele.
