Genetic inheritance follows rules. Genes are real things. All cells arise from pre-existing cells. Sex cells have one set of chromosomes; body cells have two. Specialized chromosomes determine gender. Chromosomes carry genes. Genes get shuffled when chromosomes exchange pieces. Evolution begins with the inheritance of gene variations. His professor recommended Mendel to the Augustinian monks in Brunn now Brno , who valued science, research, and education.
His professor thought he would be a good candidate because of his talent in physics and mathematics. Even though Mendel had not planned to be a monk, he was admitted to the order on September 7, Mendel was then able to continue his education at the University of Vienna where he found a talent for teaching, though interestingly he was twice unable to pass the teaching certificate examination. He was quiet and shy; he may have found the oral part of the examination too nerve-wracking.
He was at home in the monastery's botanical garden where he spent many hours a day breeding fuchsias and pea plants. Mendel's brilliance is unrecognized. His paper, "Experiments on Plant Hybridization," was published the next year. While his work was appreciated for its thoroughness, no one seemed to grasp its importance. The work was simply too ahead of its time, too contrary to popular beliefs about heredity.
Aa Aa Aa. Gregor Mendel: A Private Scientist. Gregor Mendel. Gregor Mendel's work in pea led to our understanding of the foundational principles of inheritance. Keeping the peas.
Breeding from these hybrids, he was astonished to get three types of plants: one had only green peas, one only yellowish-white, and the third kind had both green and yellowish-white in the same pod. Despite making some interesting observations, neither Knight nor Goss counted the number of peas with particular traits and consequently failed to discover the hereditary mechanism. This research became a launch pad for the start of a long history of pea research at the John Innes Institute.
Furthermore, Mendel's findings were not viewed as being generally applicable, even by Mendel himself, who surmised that they only applied to certain species or types of traits.
Of course, his system eventually proved to be of general application and is one of the foundational principles of biology. In , Mendel was elected abbot of the school where he had been teaching for the previous 14 years, and both his resulting administrative duties and his gradually failing eyesight kept him from continuing any extensive scientific work.
He traveled little during this time and was further isolated from his contemporaries as the result of his public opposition to an taxation law that increased the tax on the monasteries to cover Church expenses. Gregor Mendel died on January 6, , at the age of His work, however, was still largely unknown. Hugo de Vries, Carl Correns and Erich von Tschermak-Seysenegg each independently duplicated Mendel's experiments and results in , finding out after the fact, allegedly, that both the data and the general theory had been published in by Mendel.
Questions arose about the validity of the claims that the trio of botanists were not aware of Mendel's previous results, but they soon did credit Mendel with priority. Even then, however, his work was often marginalized by Darwinians, who claimed that his findings were irrelevant to a theory of evolution.
