Catholic Church and health care the retinal image. Gregor Mendel, an Austrian scientist and Augustinian friar, began experimenting with peas around 1856. Mendel had joined the Brno Augustinian Monastery in 1843, but also trained as a scientist at the Olmutz Philosophical Institute and the University of Vienna. The Brno Monastery was a centre of scholarship, with an extensive library and tradition of scientific research. Observing the processes of pollination at his monastery in modern Czechoslovakia, Mendel studied and developed theories pertaining to the field of science now called genetics. Mendel published his results in 1866 in the "Journal of the Brno Natural History Society", and
Plant genetics put forth by Mendel. W.E. Castle discovered that while individual traits may segregate and change over time with selection, that when selection is stopped and environmental effects are taken into account, the genetic ratio stops changing and reach a sort of stasis, the foundation of Population Genetics. This was independently discovered by G.H. Hardy and W. Weinberg, which ultimately gave rise to the concept of Hardy-Weinberg equilibrium published in 1908.
