Mendel worked as a substitute high school teacher. In 1850, he failed his exams' oral part, the last of three parts, to become a certified high school teacher. In 1851, he was sent to the University of Vienna to study under the sponsorship of Abbot Cyril František Napp so that he could get a more formal education. [17]
However, with the rediscovery of Gregor Mendel's laws of heredity, two separate camps of eugenics advocates emerged, one of statisticians, the other of biologists. Statisticians thought the biologists had exceptionally crude mathematical models, while biologists thought the statisticians knew little about biology.
The two schools were the Mendelians, such as Bateson and de Vries, who favoured mutationism, evolution driven by mutation, based on genes whose alleles segregated discretely like Mendel's peas; [21] [22] and the biometric school, led by Karl Pearson and Walter Weldon. The biometricians argued vigorously against mutationism, saying that ...
Classical genetics is often referred to as the oldest form of genetics, and began with Gregor Mendel's experiments that formulated and defined a fundamental biological concept known as Mendelian inheritance. Mendelian inheritance is the process in which genes and traits are passed from a set of parents to their offspring.
Between 1856 and 1865, Gregor Mendel conducted breeding experiments using the pea plant Pisum sativum and traced the inheritance patterns of certain traits. Through these experiments, Mendel saw that the genotypes and phenotypes of the progeny were predictable and that some traits were dominant over others. [ 14 ]
In Olomouc, Gregor Johann Mendel was one of the most favourite Franz's students. Franz immediately recognized his great talent, and they soon became good friends. They debated a number of topics, such as the origin of the solar system and of life as such, the development of Goethe's philosophy and the purpose of human life.

The Mendel Lectures are named in honour of Gregor Johann Mendel (1822-1884), the founder of genetics, who lived and worked in the Augustinian Abbey in Brno 1843-1884. Based on his experiments conducted in the abbey between 1856 and 1863, Mendel established the basic rules of heredity, now referred to as the laws of Mendelian inheritance.
