Two tall pea plants are crossed and their seeds are planted in a sunny spot in the garden. They received the same amount of water, are exposed to the same temperatures and soil conditions.

B. The amount of sunlight the plants received was different, thus some did not get enough light to grow tall.
C. The growing conditions of the plants were different, thus some did not get the resources they needed like fertilizer.
D. The plants received different genetic factors from the parents, some received the tall factor and some the short factor.
D. The plants received different genetic factors from the parents, some received the tall factor and some the short factor.
