Asexual reproduction is the production of new individuals from a single parent. This type of reproduction is generally observed in single-celled organisms. Here no fusion of gametes is involved and a single parent divides into two or more daughter cells. The offsprings produced are genetically and physically identical to the parent and are known as clones. Features of Asexual Reproduction Following are the important features of asexual reproduction: No formation of gametes or fertilization takes place. Only one parent is involved. The process occurs in very less time. The offsprings produced are exact copies of the parent, there is no variation. The growth of the offspring is rapid. Binary Fission Binary Fission In this type of reproduction, parent cell divides into two equal parts each containing a nucleus. These are called daughter cells. The daughter cells are genetically and physically similar to the parent cell. This type of asexual reproduction can be seen in organisms such as amoeba, bacteria, euglena, etc. Budding Budding in hydra Budding is another method of asexual reproduction where a new organism develops from an outgrowth from the parent body known as a bud. These derive nutrition from the parent for growth and development. Once grown, the new organism detaches from the parent body. This process is called budding. This types of reproduction can be seen in Hydra. Fragmentation This type of asexual reproduction is exhibited by Planaria. In this, the parent body breaks into several pieces where each piece grows into a new individual. The detachment of the body parts is intentional. Regeneration In this, if a part of the body of an organism is detached, the detached part grows into a completely new individual. Regeneration is observed in Echinoderms.
