Gregor Mendel & The Law of Segregation

Was a very careful worker who planned his experiments on a large scale. He recognised that by taking a large number of separate measurements, he could eliminate chance effects. Mendel chose the Pea plant to study because it had several very sharply contrasting characteristics that did not have any incomplete dominance. His first experiment was to cross a tall stem (pure breeding - homozygous) pea plant with a short stem plant. He gathered the seeds produced and planted them. He then crossed 2 of the F1 generation. From these results, he formulated the Law of Segregation. essay writing service
