I have a Genetics Queston?
A woman with dimples (D), a dominant human trait, is crossed with a male with no dimples. What more information do you need in order to figure out the answer to this question? Do both scenarios and give the genotype ratios for both.
I have the 'a' answer, I just wanted to check mine with somebody's.

"What more information do you need in order to figure out the answer to this question?"
Well, knowing what the actual question is would probably be a big help.
The woman could have two different genotypes DD or Dd. In the first case, when mating with a man with no dimples, ALL of their children will have dimples, and all with have the genotype Dd. In the second case, 1/2 of the kids will be Dd and have dimples, half will be dd and not have dimples.
Whether the traits inherited were heterozygous or homozygous.
