Asexual reproduction is a type of reproduction where fertilization does not take place as only a single parent is involved. Offspring produced is identical to the parent because they are produced as clones. Types of asexual reproduction are as follows: fission, budding and fragmentation.
A. Fission: This type is mainly seen in unicellular prokaryotes. A full-grown organism at a certain stage splits into two identical daughter organisms.
B. Budding: In this type of asexual reproduction, a 'bud' or an outgrowth is formed on the mature adult body and eventually this bud separates and acts as an individual organism.
