Gregor Johann Mendel OSA (/ ˈ m ɛ n d əl /; Czech: Řehoř Jan Mendel; [2] 20 July 1822 [3] – 6 January 1884) was an Austrian [4] [5] biologist, meteorologist, [6] mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia.
Later authors have suggested Fisher's analysis was flawed, proposing various statistical and botanical explanations for Mendel's numbers. [4] It is also possible that Mendel's results are "too good" merely because he reported the best subset of his data—Mendel mentioned in his paper that the data were from a subset of his experiments.
The Mendelian school, led by William Bateson, however thought that Gregor Mendel's work gave an evolutionary mechanism with large differences. Joan Box, Fisher's biographer and daughter states in her 1978 book, The Life of a Scientist [ 4 ] that Fisher, then a student, had resolved this problem in 1911.
Classical genetics is the branch of genetics based solely on visible results of reproductive acts. It is the oldest discipline in the field of genetics, going back to the experiments on Mendelian inheritance by Gregor Mendel who made it possible to identify the basic mechanisms of heredity.
Mendel himself warned that care was needed in extrapolating his patterns to other organisms or traits. Indeed, many organisms have traits whose inheritance works differently from the principles he described; these traits are called non-Mendelian. [44] [45] For example, Mendel focused on traits whose genes have only two alleles, such as "A" and "a".
He deduced that there is a certain tangible essence that is passed on between generations from both parents. Mendel established the basic principles of inheritance, namely, the principles of dominance, independent assortment, and segregation. 1866: Austrian Augustinian friar Gregor Mendel's paper, Experiments on Plant Hybridization, published.

As with Haldane and Fisher, Dobzhansky's "evolutionary genetics" [59] was a genuine science, now unifying cell biology, genetics, and both micro and macroevolution. [44] His work emphasized that real-world populations had far more genetic variability than the early population geneticists had assumed in their models and that genetically distinct ...
