10. Gregor Mendel
(July 20, 1822 – January 6, 1884) was an Augustinian priest and scientist, and is often called the father of genetics for his study of the inheritance of traits in pea plants.

11. Gregor Mendel
Mendel showed that the inheritance of traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognized until the turn of the 20th century (1900). Its rediscovery prompted the foundation of the discipline of genetics.
