Julie Solyar Honors Post-AP Advanced Topics in Biology Mr. Seigman December 11, 2003 DeVries, Correns, and Tschermak Three botanists, Hugo De Vries, Carl Erich Correns, and Erich Von Tschermark-Seysenegg, made possible for the spread and understanding of Mendel's work that has led to the modern understanding of the gene today. They re-discovered Mendel's laws in 1900 by independently working on plant hybrids. Their discoveries paved the way for the connection between Mendelian genetics and medicine, which was instigated by Archibald Garrod. This was complimented by greater discoveries in genetics, especially by Thomas Hunt Morgan, Herman J Muller, George Beadle, and Edward Tatum. Hugo de Vries (1848-1935) worked at the University of Amsterdam in 1880, as a professor of botany. Simultaneously, he worked on a series of genetic hybridization experiments. Working with the Oenothera lamarckiana (the evening primrose), de Vries was able to produce his theory of mutation. He agreed with discontinuous variation, staging that species...
