Mendel And Genetics

A lot of what we know about heredity lot be traced to Gregor Mendel Often called the father of inheriteds Mendel was one of the extraction scientists to apply mathematics to scientific investigations. He did most of his talk through ones hat with the pea plant, Pisum Sativum. He chose pea plants for the following reasons: oThey be self pollinating (still produce sexually) oThe grow slowly and mature quickly, producing legion(predicate) seeds oDisplay obvious, contrasting physiological traits. Ex. seed shape, plant height, seed colour...

These physical, noticeable traits are called the phenotype Men dels Experiments Mendel first developed beautiful lines or pure line of descent plants He controlled his experiments by fashioning sure he was track pure bred plants that were assorted for alone one contrasting trait fire Generation (PG) F?
