Dislike Broccoli? -- Blame it on Your Genes!

Alleles of the TAS2R38 taste receptor gene can confer the phenotypic ability to taste the chemical Phenylthiocarbamide (PTC) and other bitter flavors. Students will PCR amplify their own TAS2R38 taste receptor gene and use DNA restriction analysis to determine whether they have a taster or non-taster version of the gene. Determinations can be made as to their genotype for this trait, and correlate that genotype with the ability to taste PTC (and foods that contain related chemicals, such as broccoli)
