Particulate inheritance traits are inherited from one generation to the next. Blending inheritance was the common ideal at the time, but was later discredited by the experiments of Gregor Mendel. Mendel proposed the theory of particulate inheritance by using pea plants ("Pisum sativum") to explain how variation can be inherited and maintained over time. Since Mendel used experimental methods to devise his particulate inheritance theory, he developed three basic laws of inheritance: the Law of Segregation, the Law of Independent Assortment, and the Law of Dominance: Mendel's experiment with tall and short pea plants demonstrates how each individual plant has two particles
Role of Christianity in civilization contribute to a deeper understanding of revelation, and so encouraged intellectual development. The Church's priest-scientists, many of whom were Jesuits, have been among the leading lights in astronomy, genetics, geomagnetism, meteorology, seismology, and solar physics, becoming some of the "fathers" of these sciences. Examples include important churchmen such as the Augustinian abbot Gregor Mendel (pioneer in the study of genetics), the monk William of Ockham who developed Ockham's Razor, Roger Bacon (a Franciscan friar who was one of the early advocates of the scientific method), and Belgian priest Georges Lemaître (the first to propose the Big Bang theory).
