The BIG contributors to our ideas about Genetics

Mendel Gregor Johann Mendel 1822 – 1884 An Augustinian friar Austrian Father of modern science of Genetics. Significance of his work not discovered for 3 decades

Mendel’s Peas Mendel worked laboriously on peas for his studies of inheritance. He chose 7 traits: seed shape, flower color, seed coat tint, pod shape, unripe pod color, flower location, and plant height. From his studies of these traits, he proved that invisible factors (later called genes) were inherited and passed onto next generations. He coined the phrases ‘dominant’ and ‘recessive’. He established the ‘Laws of inheritance’.
