Nutritional reproduction can make offspring keep their parents' traits. Therefore, people often use rooting, cutting and grafting to propagate flowers and fruit trees.

In production and scientific research, asexual reproduction is often used to propagate fine varieties and cloned organisms. Vegetative reproduction mainly starts from the vegetative organs of the mother and gradually leaves the mother. After a series of cell division and differentiation, it gradually became a new individual. Its genetic information comes entirely from its mother, so it can only keep its mother's shape. Because the starting point of its formation is the vegetative organ of the mother, it can speed up the birth rate, while the starting point of zygote is from the fertilized egg, so it can not be born soon. Because vegetative reproduction can only inherit the genetic traits of the mother, the variation is small, so the vitality of the offspring gradually decreases and may eventually become extinct.
