Question

Which of the following observations led Mendel to conclude that some traits were recessive? A. Plants with a certain form of each trait were more likely to survive and reproduce than plants with other forms of each trait. B. The offspring produced during his first set of experiments expressed one form of a trait, while the offspring produced during his second set of experiments expressed a different form of the trait. C. When he crossed plants that expressed different forms of a trait, one form always "disappeared" and never "reappeared in later generations. D. The form of a trait that seemed to "disappear" during his first set of experiments "reappeared" during his second set of experiments.
