Q
Reproduction in Animals

Question:

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

Answer:

The production of new organisms from a single parent without the involvement of sex cells or gametes is called asexual reproduction. Example: Amoeba and Hydra. The young produced by asexual reproduction is an exact copy of the parents.

The two most common methods of asexual reproduction are:

1. Binary fission – The mode of asexual reproduction in which an animal reproduces by diving into two individuals is called binary fission. Example: Amoeba.

2. Budding – Budding is an asexual reproduction in which a small part of the body of the parent organism grows out as a bud which then detaches and becomes a new organism. Example: Hydra.
