Define asexual reproduction. Describe the two methods of asexual reproduction in animals.

Answer:

Asexual reproduction is that type of reproduction in which only single parent is involved. Asexual reproduction takes place by different methods like budding, binary fission etc. Let us discuss these two methods:  (i) Budding: In budding, a new organism is formed as an outgrowth from the parent body. In Hydra, a small bulge appears from the lower part of the body. This grows into a bud, detaches from parent body and develops into a young Hydra. (ii) Binary fission: In this type of reproduction, a single organism gets divided into two. This type of reproduction takes place in Amoeba. The nucleus of the Amoeba gets divided into two followed by division of its body, each part getting one nucleus and developing into separate individual.
