Students investigate the inheritance of the ability to taste sodium benzoate by constructing a pedigree of the ability of members of their family to taste them. Includes: 1 vial sodium benzoate, 1 vial control papers (100 papers per vial), and a family pedigree chart. *Test Paper Factoid: Taste papers can be used to demonstrate inheritance. The ability to taste PTC is a hereditary trait. 7 out of 10 people will taste it. Sodium Benzoate tastes sweet, salty, bitter or will be tasteless to different people. Thiourea tastes bitter to most but is tasteless to some!
