Gregor Mendel (1822–1884): Gregor Mendel was an Augustinian monk and botanist whose experiments in breeding garden peas led to the establishment of the fundamental laws of genetics. Born in the early 19th century in what is now the Czech Republic, Mendel’s meticulous work with pea plants laid the foundation for the field of genetics. He demonstrated that the inheritance of certain traits in the plants follows particular patterns now referred to as the laws of Mendelian inheritance. His most significant contributions include the Law of Segregation which states that an individual inherits one allele from each parent for each trait. His Law of Independent Assortment pose that traits are passed independently of one another from parents to offspring. Mendel’s work was largely unrecognized during his lifetime but was rediscovered and confirmed in the early 20th century cementing his status as the “father of modern genetics.”
