Engage students with a genetics and PCR kit that has a direct link to a testable phenotype. Students are tested for their ability to taste phenylthiocarbamide (PTC), a substance that either tastes very bitter or relatively tasteless depending on the genetics of the taster. Students taste a sample of PTC and extract their own DNA and through PCR compare their phenotypic result to their genotypic result.

  • Direct relation between phenotype and genotype - excellent for teaching the impact of genetic makeup.

  • Simple and fast - As with all GenoSensor educational products, we've worked hard to keep things easy to set up and fast to use, all while providing reliable results.

  • It's fun! Students will love being able to test their own DNA and have a tangible link to the test.
