For a class of 32 students working in pairs. Give your students the opportunity to grasp the impact of genes on phenotypic 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 inheritance. Kit includes teacher's manual and reproducible student guide.
