In this way, Mendel's work was quite different from that before him. By assuring that he had pure-breeding plants to start, he made certain that his results were reproducible. Unlike Knight, Mendel employed a rigorous scientific strategy when devising his experiments. When Mendel tried to repeat Knight's experiments, he spent two years generating pure-breeding plants for each of the seven traits he followed, and then carefully counted plants with each trait after the parental plants were systematically crossed and then self-pollinated. Those studies, however, did not include rigorous backcrossing of the starting plants to generate pure-breeding parental strains, nor were the number of different colored peas in the offspring carefully recorded. For example in the 1800s, Thomas Andrew Knight published nearly 100 articles on the subject of horticulture, including an article about inheritance in pea plants, pre-dating Mendel's work by three decades. Horticulturalists had long published plant-breeding experiments that superficially resembled those of Mendel. Perhaps part of the answer is that Mendel's studies did not appear novel. How could Mendel's important work have been all but forgotten for nearly a generation? In 1900, Mendel's work was rediscovered by three people, Hugo de Vries, Carl Correns, and Erich Tschermak von Seysenegg, who independently popularized and extended the studies. People failed to appreciate its rigor and its implications for the scientific understanding of inheritance, breeding, evolution and cell biology.
