Mendel who is he

It was during this time that he began the experiments for which he is best known. Around , Mendel began to research the transmission of hereditary traits in plant hybrids. Mendel chose to use peas for his experiments due to their many distinct varieties, and because offspring could be quickly and easily produced. He cross-fertilized pea plants that had clearly opposite characteristics—tall with short, smooth with wrinkled, those containing green seeds with those containing yellow seeds, etc.

He also proposed that this heredity followed basic statistical laws. In , Mendel delivered two lectures on his findings to the Natural Science Society in Brno, who published the results of his studies in their journal the following year, under the title Experiments on Plant Hybrids.

Mendel did little to promote his work, however, and the few references to his work from that time period indicated that much of it had been misunderstood. It was generally thought that Mendel had shown only what was already commonly known at the time—that hybrids eventually revert to their original form. The importance of variability and its evolutionary implications were largely overlooked. 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. At the time, it was widely believed that heredity worked by blending the characteristics of parents, producing offspring that were in some way diluted. Mendel showed that when two varieties of purebred plants cross-breed, the offspring resembled one or other of the parents, not a blend of the two.

He found that some traits are dominant and would always be expressed in a first generation cross, while others are recessive and would not appear in this generation. However, these recessive traits re-appear in the next generation if these first-generation plants self-fertilise. Mendel hypothesised that parents contribute some particulate substance to the offspring which determine its heritable characteristics. We now know that these particles correspond to genes made of DNA.

Without any knowledge of the molecules involved, Mendel was able to infer that heritable particles are separated into gametes — eggs and sperm — and that offspring inherit one particle from each parent.
