To Taste or Not to Taste

In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart findings from all learners to determine which trait is dominant. Although this activity was created as a post-visit for a workshop about genetics, it also makes an excellent stand alone activity.
