Human Genetics Taste Papers
Acquiring a Taste for Genetics • Teach analysis and testing techniques
• Study dominance/recessiveness • Learn the relationship between phenotype and genotype
• Use for genetics studies, science fair projects, and food preference studies
This hands-on (or taste buds-on) assignment is a great way to involve your entire class in a classic human genetics experiment. Students simply test whether or not they can taste the chemical in the taste paper. The ability to taste the chemical is an inherited trait that varies throughout the population, giving you good genetic data. Exercises also teach students Punnett square and pedigree analysis, as well as chi-square testing. Matchbook-style taste papers make it easy to use just one piece at a time.
Customer Review
“This was a great part of lessons . . . It was amazing to see how each [student] reacted to the taste of these papers. Even though we are all alike, there is so much about us that is different.”

: Human Genetics of Taste
For a class of 32 students working in pairs. Students investigate the frequency of genetically controlled traits within their classroom population. By exploring taste response traits and recording classroom data, students are able to conduct a Hardy-Weinberg analysis of their classroom. Kit includes multiple types of sample test paper (including paper treated with PTC, sodium benzoate, and thiourea, as well as a control paper to help reinforce experimental design) plus teacher’s man- ual and reproducible student guide.
Kit includes: Control Taste Paper
Sodium Benzoate Taste Paper
Teacher’s Manual and Reproducible Student Guide
173850 Per kit 174030 Thiourea Paper Carolina BioKits® : Human Genetic Traits
For a class of 32 students working in pairs. Give your students the opportunity to grasp the impact of genes on pheno- typic traits by investigating their frequency in the classroom. Engage your students with classical human inheritance traits like tongue rolling, widow’s peak, PTC taste, and much more. Using information from their own classroom data and provided research, students investigate these traits and attempt to identify whether they follow Mendelian inheri- tance. Kit includes teacher’s manual and reproducible student guide.
