Rediscovery of Mendel It was in 1900 that Mendel’s laws were rediscovered by three different scientists from different countries. They were Hugo de Vries (Holland), Carl Correns (Germany) and Erich von Tschermak (Austria). The pioneering work of Mendel was highly important, and its impact was so deep that after his findings the world of genetics was divided into two eras: Mendelian genetics and post-Mendelian genetics, regarding the progress made after him in this field.


• Carl Correns raised the status of two of Mendel’s generalizations to the level of Laws. • The factors of Mendel are now called genes. The term gene was coined by Wilhelm Johannsen (1909).
