Reproduction In Animals

Introduction:

Reproduction in animals encompasses the diverse processes through which different species give rise to new generations, ensuring the continuity of their respective populations.

It can be classified into two primary types: sexual reproduction and asexual reproduction.

Asexual Reproduction:

Asexual reproduction is a mode of reproduction where offspring are produced without the involvement of gametes (sex cells). It includes various methods:

1. Fission (Splitting):

A single parent organism divides into two or more identical offspring.

Binary Fission – One parent cell divides into two daughter cells; commonly seen in bacteria.
Multiple Fission – A single parent cell gives rise to more than two offspring; observed in certain protozoa.

2. Budding:

A small outgrowth (bud) forms on the parent organism, eventually detaching and developing into a new individual.

3. Fragmentation:

An organism breaks into fragments, each capable of regenerating into a complete individual.
