Problem
In man, the ability to taste substance phenylthiocarbamide (PTC) is inherited as a dominant characteristic (T). To tasters, PTC is bitter, nontasters (t) find it tasteless. Albinism (a), on the other hand, is inherited as a recessive trait. A couple, both tasters (T) and normally pigmented (A), married and their first child is an albino and a nontaster. What are the genotypes of the parents?
