Ptc Paper, Pack Of 100 Strips, Use For Genetic Studies And Science Fair Projects

Product Details PTC (Phenylthiocarbamide) paper provides a fantastic firsthand demonstration of genetics that your students will never forget. Simply have students place a PTC strip on their tongue, wait, and see the reactions of those who can taste the bitter PTC molecule and those that taste nothing at all! Seven out of 10 people can taste PTC and 3 out of 10 cannot, making this phenomena a fantastic topic for learning the relationships between phenotype and genotype, dominant and recessive genes, and other genetic concepts.
