Gregor Mendel pod shape, unripe pod color, flower location, and plant height. He first focused on seed shape, which was either angular or round. Between 1856 and 1863 Mendel cultivated and tested some 28,000 plants, the majority of which were pea plants ("Pisum sativum"). This study showed that, when true-breeding different varieties were crossed to each other (e.g., tall plants fertilized by short plants), in the second generation, one in four pea plants had purebred recessive traits, two out of four were hybrids, and one out of four were purebred dominant. His experiments led him to make two generalizations, the Law of
Order of Saint Augustine the members of the order, but it was the great scientist Johann Gregor Mendel, abbot of the Czech monastery of St. Thomas at Old Brno in Moravia (d. 1884) who gave great credit to the Augustinian Order's scholarship in the 19th century. He was the discoverer of the Mendelian laws of heredity and hybridization. Given that the Roman Catholic Church in the Western world has been experiencing a decline in vocations to the priesthood and religious life since the 1960s, a relatively simple way to assess the vigour of this order is to compare the numbers of those in solemn
