in humans, the ability to taste a chemical called PTC is due to a dominant allele, T while the inability to taste this substance is due to the recessive allele t. Additionally, the allele for brown eyes, B, is dominant over the allele of blue eyes, b. A man who is a waster with brown eyes marries a woman who is a taster with blue eyes. They have a daughter who is a non taster with brown eyes and a son who is a taster with blue eyes. The son marries. Two of his children are tasters wit brown eyes, and the other is a non taster with brown eyes.

Can someone help me with finding out HOW in the world to do a pedigree on this? What is the genotypes of each person? HELP !!!!
