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

         DB       Db         dB        db

dB   DdBB   DdBb    ddBB    ddBb

dB   DdBB   DdBb    ddBB    ddBb

db    DdBb    Ddbb    ddBb    ddbb   

db    DdBb    Ddbb    ddBb    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%)
