Assuming you mean to type:
"In humans, the allele for dimples (D) is dominant to
the allele for no dimples (d). at another gene locus, the allele for broad
eyebrows (B) is dominant to the allele for broad eyebrows (b)."
Man: Heterozygous for both genes means DdBb
Woman: no dimples, and heterozygous for slender eye-brows
means ddBb

Interpretation: anywhere that has a capital letter has the
dominant trait.
Dimples+Broad eyebrows : 6 cases out of 16 (3/8=37.5%)
Dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)
No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
