At Bruno, Mendel began his studies with pea plants. During a seven year period between 1856 and 1863 he conducted experiments on 28, 000 pea plants. From his research he developed the terminology for modern day genetics, including dominant and recessive traits.
He published his work on heredity in 1866. His work was largely ignored by the scientific community for the next three decades. In 1900 a Dutch botanist Hugo DeVries recognized the significance of Mendel's work.
Later in his career, Mendel investigated hawkweed. He ceased his experiments in 1870, fourteen years before his death. Gregor Mendel died in Brunn on January 6, 1884. His work was not recognized until after his death.
