Uniparental inheritance the days of an Augustinian priest known as Gregor Johann Mendel. The soon-to-be "father of modern genetics" spent his days conducting hybridization experiments on pea plants("Pisum sativum") in his monastery's garden. During a period of seven years (1856 to 1863), Mendel cultivated and tested some 29,000 pea plants which led to him deducing the two famous generalizations known as Mendel's Laws of Heredity. The first, the law of segregation, states that "when any individual produces gametes, the copies of a gene separate, so that each gamete receives only one copy". The second, the law of independent assortment, states that "alleles
Catholic Church and health care them clergymen) made a number of important discoveries which aided the development of modern science and medicine. Saint Albert the Great (1206–1280) was a pioneer of biological field research; Desiderius Erasmus (1466-1536) helped revive knowledge of ancient Greek medicine, Renaissance popes were often patrons of the study of anatomy, and Catholic artists such as Michelangelo advanced knowledge of the field through sketching cadavers. The Jesuit Athanasius Kircher (1602 – 1680) first proposed that living beings enter and exist in the blood (a precursor of germ theory). The Augustinian Gregor Mendel (1822-1884) developed theories on genetics for the first time. As
