The laws of heredity were discovered by Gregor Mendel in about 1856-1863. Mendel conducted experiments in plant hybridization, collecting the results of cross-fertilizing hundreds of edible pea plants. The results from Mendel’s experiments confirmed his ideas about heredity: the law of segregation, which has become known as Mendel’s First Law, and the law of independent assortment, also known as Mendel’s Second Law.
