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
Dominance (genetics) their associated phenotypes; one allele can be dominant over a second allele, recessive to a third allele, and codominant to a fourth. Also, an allele may be dominant for a particular aspect of phenotype but not for other aspects influenced by the same gene. Dominance differs from epistasis, a relationship in which an allele of one gene affects the expression of another allele at a different gene. The concept of dominance was introduced by Gregor Johann Mendel. Though Mendel, "The Father of Genetics", first used the term in the 1860s, it was not widely known until the early twentieth century.
