Use for genetic studies, science fair projects and food preference studies PTC Phenylthiocarbamide (phenylthiourea) is an organic compound that either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. The ability to taste PTC is a dominant genetic trait. The test to determine PTC sensitivity is one of the most common genetic tests on humans. The Frey Scientific 569885 PTC Taste Paper is a paper test strip for students to investigate genetically determined taste responses and to study genetic transfer of dominant and recessive genes and random segregation, is impregnated with phenylthiocarbamide (PTC) which detects the presence or absence of a single gene, and comes in a clear plastic stoppered vial for transport and storage.
