Quizplus · Accepted Answer

Cross-fertilization involves the transfer of pollen from one plant to the egg of another plant, promoting genetic diversity. Self-fertilization, not explicitly defined in the options but implied by elimination, involves the pollen from a plant fertilizing an egg of the same plant, leading to less genetic variation.
