Question

Did you know that dimples (D) are the phenotype of the dominant allele? If you have dimples what are your possible genotypes? (D is dominant, d is the recessive allele)(1 point)

DD, Dd, or dd

Answer 1

If dimples (D) are the phenotype of the dominant allele, and you have dimples, your possible genotypes are:

**DD or Dd**

This is because a person with dimples could either have two dominant alleles (homozygous, DD) or one dominant allele and one recessive allele (heterozygous, Dd). The homozygous recessive genotype (dd) would not express the dimple phenotype.
