In humans, the presence or absence of dimples is a trait controlled by a single gene. what is the genotype of an individual who is heterozygous for dimples?

If we let the "D" represent the allele for dimples, and "d" represent the allele for no dimples, then Dd would be the genotype of an individual who has both alleles, therefore being heterozygous.
