Man's genotype is Dd and women's genotype Dd.

Man's phenotype = dimple

woman's phenotype = dimple

Explanation:

Dimples are usually considered a dominant trait, this means that the presence of a dominant allele will pass the trait of the dimple to the progeny.

Dimples are dominant traits that are said to be irregular as the trait appearance is affected by other genes also.

The allele dominant for dimple will pass the trait and those with recessive allele will have no dimple is the logic.
