You fertilize egg cells from a healthy plant with pollen (which contains the male germ cells) that has been treated with DNA-damaging agents.You find that some of the offspring have defective chloroplasts, and that this characteristic can be passed on to future generations.This surprises you at first because you happen to know that the male germ cell in the pollen grain contributes no chloroplasts to the fertilized egg cell and thus to the offspring.What can you deduce from these results?
