    When a tall homozygous plant was crossed with a short homozygous plant, the F1 offspring were all tall. No short plants were present in the F1 generation. Which principle does this situation represent? The principle of unit characters The principle of dominance The principle of segregation

    This situation represents the principle of dominance. The principle of dominance is when all the offspring express only the dominant trait. Because the offspring were all tall, and no short plants were present, the tall dominated over the small, therefore it is the principle of dominance.
