How did Carl Erich Correns contribute to the rediscovery of Gregor Mendel’s laws?

Carl Erich Correns contributed to the rediscovery of Gregor Mendel’s laws by independently arriving at the same conclusions through his own research on garden peas while working at the University of Tübingen between 1892 and 1902.1

Upon surveying existing literature to validate his findings, Correns discovered Mendel’s original 1866 paper, which had been largely overlooked for decades. Although he had previously read Mendel’s work and even taken detailed notes on it, he had forgotten the specifics until his own experiments mirrored those results.12

Following this 1900 rediscovery—which occurred simultaneously with the work of Hugo de Vries and Erich Tschermak von Seysenegg—Correns became a vital advocate for Mendelian theory. He provided an overwhelming body of evidence to support Mendel’s thesis and furthered the field by investigating the limits of these laws, eventually identifying the first conclusive example of cytoplasmic inheritance.12
