When a plant reproduces vegetatively its offspring are genetically identical to the original plant. Vegetative reproduction does not utilize meiosis; it does not involve the recombination of chromosomes with another organism. Vegetative reproduction involves only mitosis--the chromosomes are duplicated before the cells divide, producing cells that are identical to the parent plant. This can also happen in animals; for example, when starfish produce an entirely new starfish from a piece of the original. Mostly we think of it in bacteria and plants. In plants, it frequently takes the form of runners or sucker shoots; people often take clippings of plants and grow new, identical copies.
Many plants are able to produce individuals asexually, without producing seeds. Therefore, there is no pollination, fertilisation or gametes. This form of asexual reproduction is called vegetative propagation.
The offsprings produced are genetically identical to its parent as well as others. Because it does not undergo the process of meiosis, where changes may occur genetically.
