Define asexual reproduction. Describe the two methods of asexual reproduction in animals.
Asexual reproduction is that type of reproduction in which only single parent is involved. It takes place by different methods like budding, binary fission etc.
(i) Budding : In this type of reproduction new individuals develop from the buds. For example - reproduction in 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 divides into two, followed by division of their bodies, each part getting one nucleus and developing into separate individual.
