Gregor Mendel spent eight years crossbreeding pea plants in a monastery garden in Brno, meticulously counting wrinkled and smooth seeds, tall and short stems. His results revealed the fundamental laws of heredity — dominant and recessive traits, the ratios that govern inheritance — but the scientific world ignored him completely. He died in obscurity, and his work was not rediscovered for thirty-five years.

This episode traces Mendel from his peasant childhood through his monastic life and the painstaking pea plant experiments, examining why the father of genetics was ignored in his own lifetime and how his rediscovery launched modern biology.
