Test the genetically-determined taste response of students and families
PTC only has a taste to 7 out of 10 people and different genes determine if you can taste sodium benzoate. If it tastes salty, bitter, or sweet to you, then you have the dominant gene (S-). If you don't taste anything, you are recessive (ss).
Thiourea may have taste if you can taste PTC
Perfect for a demonstration of genetics, heredity, and taste testing
