The ability to taste the bitter chemical Phenylthiocarbamide (PTC) is a dominant trait. "Tasters" are either TT or Tt. "Non-tasters"are homozygous recessive, tt. Felix and Felicity just started dating and invite their parents over for a get-to-know-you holiday dinner party. Felicity just finished her second-year genetics course earlier that month and managed to sneak out some PTC paper. Both Felix and Felicity can taste the bitter PTC paper, as can both of their mothers. However, neither Felix's or Felicity's fathers can taste the paper...it just tasted like plain old newsprint. Felicity pulls out a $100 bill and offers it to the parent that can guess the chances that Felix and Felicity have a child that is a "taster"
