Document Summary
Gregor mendel: an austrian monk who discovered the basic principles of heredity by breeding garden peas in carefully planned experiments. Dna: mendel"s idea was published 1866 decades before chromosomes ere observed in the microscope and almost 100 years before the identi cation of. Dna as the inheritable genetic material: mendel chose garden peas for his genetic experiments because: They produced many offspring from each mating. There are many varieties with distinct inheritable characters, such as ower color, pea shape, etc: each character has more than one trait (the different variants, such as purple or white owers) Plants that always produce offspring of the same variety when bred to themselves. The offspring of matings (crossings) between plants expressing different traits. Mendel & the law of segregation: states that the two alleles for an inheritable character separate (segregate) during gamete formation and end up in different gametes.
