... Mendel crossed two pea plants that differed in only one trait—height. He crossed purebred tall plants with purebred short plants. The offspring of this cross, which Mendel called the first filial, or F1, generation, were all tall. It seemed as if the shortness trait had disappeared. When the F1 plan ...
