1 janv. 1865 - 1865: Gregor Mendel identifies discrete units of heredity.

Description:

Gregor Mendel holds a flower, possibly from a pea plant, in his monastery garden in Brno (now in the Czech Republic). Mendel’s seminal experiments in the 1850s and ’60s identified indivisible particles of information as carriers of hereditary information. Mendel’s paper (1865) was largely ignored for four decades, and then transformed the science of biology.
