MENDEL, GREGOR JOHANN. "Versuche über Pflanzen-Hybriden" [in:] Verhandlungen des naturforschenden Vereines in Brünn. IV. Band 1865. Brno: Verlage des Vereines 1866. 8vo, 220 x 147 mm., contemporary purple half-cloth spine faded, board edges slightly rubbed, library ink-stamp on title.

3:1 and 9:3:3:1 = the foundation of genetics. Mendel "crossed tall with dwarf sweet peas and bred from their stock. Instead of producing, as might have been anticipated on a priori reasoning, a plant of intermediate height, all the offspring were at least as tall as the tall parent. The seeds of the tall hybrids, however, produced a surprisingly different generation of which three-quarters were tall and one-quarter dwarf. All the dwarfs and one-third of the talls bred true: two-thirds of the talls behaved exactly like the second generation." -- Printing and the Mind of Man. Mendel's work was championed by William Bateson who began the era of twentieth century genetic research in 1909 with his work Mendel's Principles of Heredity.
