Correns Cor·rens (kôr'əns), Karl Erich. 1864-1933.
German botanist and geneticist whose research led to the rediscovery (1900) of Mendel's law of inheritance.
The first case I choose is not the one given by Mendel but one worked out later by correns.
It contains a number of important facts and discussions and has inspired the experimental researches of correns and others.
