Mendel Found That Tall Pea Plants Are Genetically Dominant Over

Mendel found that tall pea plants are genetically dominant over short pea plants. This means that

A) Tall pea plants produce many more peas than short pea plants.
B) Even if a pea plant contains just the genes for shortness, it still might be tall.
C) A tall pea plant will overpower and kill off a short pea plant next to it.
D) If you breed two tall pea plants, it's impossible to produce a short pea plant.
E) If a plant contains a tall and a short gene, the plant will be tall.
