PLEASE HELP BY TONIGHT: The ability to taste phenylthiocarbamide (PTC) is controlled in humans by a single dominant allele (T). A woman who is a nontaster married a man and they had three children, two boy tasters and a girl nontaster. All the grandparents were tasters. Create a pedigree of this family of this trait. Solid symbols should signify nontasters. Where possible, indicate whether the tasters are TT or Tt.
