Gregor Mendel, the Moravian Augustinian monk who founded the modern science of genetics. Mendelian inheritance is a type of biological inheritance that follows the laws originally proposed by Gregor Mendel in 1865 and 1866 and re-discovered in 1900. These laws were initially very controversial.
Johann Gregor Mendel (1822-1884) Father of Genetics. Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance.
