Gregor Johann MendelMisja Prins Biology III. B. Period 312/14/96 Gregor Mendel was one of the first people in the history of science to discover genetics. He independently discovered his work and lived in Brunn, Czechoslovakia. In Brunn he was a monk and later the Abbot of the church in Brunn. While he was in Brunn he performed many experiments with garden peas.
With the information he observed he wrote a paper where he described the patterns of inheritance in terms of seven pairs of contrasting traits that appeared in different pea-plant varieties. All of the experiments he performed utilized the pea-plant, which in this case is the basis of the experiment. Mendels work was reported at a meeting of the Brunn Society for the Study of Natural Science in 1865, and was published the following year. Mendels paper presented a completely new and unique documented theory of inheritances, but it did not lead immediately to a cataclysm of genetic research.
The scientists who read his papers of complex theories, dismissed it because it could be explained in such a simple model. He was rediscovered by Hugo de Vries in The Netherlands, Carl Corres in Germany, and Erich Tschermak in Austria all at the same time after 1900. They named the units Mendel described ‘genes.’ When the gene has different base sequence it is called an ‘allele.’ Mendel also developed 3 laws or principles. The first principle is called the, ‘Principle of Segregation.’ This principle states that the traits of an organism are determined by individual units of heredity called genes. Both adult organisms have one allele from each parent, which gives both organisms 2 alleles. The alleles are separated or ‘segregated’ from each other with the reproductive cell formation.
The Essay on Gregor Mendel for Kids
Gregor Mendel, also known as “The Father of Genetics” was an Austrian monk that made a huge discovery about genetics because of his mini garden full of pea plants. What made Mendel come to this experiment was because of the different phenotype or traits of the pea plants. Some were tall and some were short. Some plants either had purple or white flowers. Gregor observed each trait and ...
Mendel’s second principle is the, ‘Principle of independent assortment.’ This principle states that the expression of a gene for any single trait is usually not influenced by the expression of another trait. Mendel’s third and last principle is called the, ‘Principle of dominance.’ This principle states that an organism with contrasting alleles for the same gene, has one allele that maybe dominant over the other (as round is dominant over wrinkled for seed shapes in pea-plants).
All the principles just stated are Mendel’s Laws of genetics.
