In the 1860s, the Austrian Augustinian monk became interested in studying plant hybridization and began to conduct experiments on peas. The result of these studies was the famous laws of Mendel, which determined the vector of development of biology, and a little later genetics. A few decades later, a fan of eugenics (by the way, it was he who suggested using this term) F. Galton decided to study the principles of heredity in people. The works of G. Mendel and F. Galton told the world about what mysterious heredity is, what does the word talent really mean?
