When Mendel crossed plants that were purebred purple-flowered with plants that were purebred white-flowered, the resulting offspring all had purple flowers. When allowed to self-pollinate, this F1 generation gave rise to white-flowered plants as well as purple. As a result, Mendel determined that individual traits are
. inherited as discrete units.
. diluted in offspring.
merged with successive generations.
lost in the pollination process.
