Observed in both plants and animals, Fragmentation is a type of asexual reproduction in which the original organism splits into two or more parts, and each part becomes a fully-formed organism genetically identical to the original. This serves many organisms that live in hostile or dangerous environments, as the organism can recover from damage and even propgate because of it. This is normally seen in biologically non-complex organisms such as starfish and sponges, and in plants such as willow trees and cacti. Mushrooms, molds, and corals also practice fragmentation, allowing them to reproduce more rapidly than with sexual reproduction. However, because fragmentation does not create genetic diversity, it can cause genetic issues in the offspring as well as the inability to adapt to altered habitats.
eg: Seastars, sea anemones, certain types of worms, and unicellular yeast.
