Genetics Science Fair Project

Uncovering Taste Genetics

Uncovering Taste Genetics | Science Fair Projects | STEM Projects
Are you a taster or a non-taster? Find out by testing yourself and your family members with taste papers. See if you can determine if this trait is dominant in your family and in the general population.


The hypothesis is that people have genetically inherited tasting abilities.

Method & Materials

You will distribute taste papers to yourself and family members, record the results, and graph the data.
You will need PTC Taste Paper, Sodium Benzoate Taste Paper, Thiourea Taste Paper, Control Taste Paper, paper cups of water, notebook paper, pencils, and envelopes.


After testing yourself and your family members, you can use the data to predict which trait (taster or non-taster) is dominant in your family and in the general population. You may also observe that certain traits, such as obesity, may be linked to being a taster or a non-taster.

Why do this project?

This science project is interesting and unique because it involves the whole family in the process of determining whether an individual can be classified as a taster or a non-taster.

Also Consider

Experiment variations to consider include constructing a Punnett Square using the information collected from parents, and testing to see if people who tend to be overweight are tasters, or if thinner people are non-tasters.
