The term for organisms that are produced from a single parent without sexual reproduction is asexual reproduction. This process allows organisms to reproduce without the involvement of gametes (sperm and egg cells), leading to offspring that are genetically identical to the parent (clones). Asexual reproduction is common in many species, including bacteria, some plants, and certain animals like sponges and hydra. Methods of asexual reproduction include binary fission, budding, and vegetative propagation. This reproductive strategy enables rapid population growth and survival in stable environments, as it does not rely on finding a mate.
