Pea diminish leaf and stem growth. Adult weevils feed on the leaves and create a notched, "c-shaped" appearance on the outside of the leaves. In the mid-19th century, Austrian monk Gregor Mendel's observations of pea pods led to the principles of Mendelian genetics, the foundation of modern genetics. He ended up growing and examining about 28,000 pea plants in the course of his experiments. Mendel chose peas for his experiments because he could grow them easily, develop pure-bred strains, protect them from cross-pollination, and control their pollination. Mendel cross-bred tall and dwarf pea plants, green and yellow peas, purple and white
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
