Part of the allure of Mendel as a hero of modern science is that we can picture him puttering in his garden, seeking answers to universal questions in his crops of peas. To some extent, Mendel’s story is primarily the story of a gardener, patiently tending his plants, collecting them, counting them, working out his ratios, and calmly, clearly explaining an amazing finding—then waiting for someone to understand what he was talking about. It is the story of a gentle revolutionary who was born a generation too soon.
