In asexual reproduction, there is no need for the fusion of male and female gametes. It is a mode of reproduction in which only a single parent is involved.

Two methods of asexual reproduction in animals:

(i) Binary fission: In this type of asexual reproduction, a single-cell organism is divided into two halves. Amoeba can reproduce by this method. It begins the reproduction process by dividing its nucleus into two nuclei. This is followed by the division of its body into two, each part receiving a nucleus. Finally, two amoebas are produced from one parent amoeba

(ii) Budding: In this method, the development of new individuals is by the bulges, and they are called buds formed on the parents.

This type of asexual reproduction is common in Hydra. In hydra, the new individuals develop as outgrowths (called buds) from a single parent. While being attached to the parent, it develops into smaller individuals, and when it matures, it detaches from the parent and becomes an individual.
