A plant grows faster and fuller due to large amounts of fertilizer. If the plant cross-pollinates with another plant later, how will the use of fertilizer on the parent plant affect the plant's offspring? All of the offspring will be taller than average because the parent plant’s genes were affected.
Some of the offspring will be taller than average because some of the alleles were affected.
The height of the offspring will not change because the parent's genes did not change.
The height of some of the offspring will be taller if the other parent plant was also fertilized.
