Abstract
In this PowerPoint-based clicker case, developed for use in either a general biology or general genetics class, students are introduced to the life and work of Gregor Mendel. The initial slides set up the story as we see Mendel, who is ill, reminiscing about his pea plant experiments. As the storyline unfolds, students are placed in a position where they have to think their way through some data the way that Mendel presumably had to do himself. The case covers the highlights of early genetics including monohybrid and dihybrid crosses, and discusses the downfall of the blending hypothesis.
