 | | During that year, three botanists, Hugo de Vries, Carl Correns, and Erich Tschermak, reported on their breeding experiments of the late 1890s and claimed to have confirmed the regularities in the transmission of characters from parents to offspring that Mendel had already presented in his seminal paper of 1865 (Olby 1985, 109-37). |
 | | As late as 1933, on the occasion of his Nobel address, he declared: “At the level at which the genetic experiments lie it does not make the slightest difference whether the gene is a hypothetical unit, or whether the gene is a material particle” (Morgan 1935, 3). |
 | | Kühn viewed his experiments as the beginning of a reorientation of what he perceived as the new preformationism of transmission genetics of his day. |
