Experiments on Plant Hybridization Experiments on Plant Hybridization "Experiments on Plant Hybridization" (German: "Versuche über Pflanzen-Hybriden") is a seminal paper written in 1865 and published in 1866 by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics. The paper was the result after years spent studying genetic traits in "Pisum sativum", the pea plant. Mendel read his paper to the Natural History Society of Brünn. It was published in the "Proceedings of the Natural History Society of Brünn" the following year. In his paper, Mendel compared pairs of discrete traits: Through experimentation, Mendel discovered that one inheritable trait would invariably
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.
