List any four specific characteristics of asexual reproduction

Genetically identical
No fertilisation
Quick method of reproduction

Explanation:
Genetically identical

Offspring are genetically identical (clones) to one another. This is an advantage when the parent is well adapted in their environment.
No fertilisation

Asexual means it does not involve gametes (sex cells) and fertilisation
Quick method of reproduction

Bacteria can produce an offspring in about 20 minutes

Asexual reproduction needs only one parent, unlike sexual reproduction, which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information. As a result, the offspring are genetically identical to the parent and to each other. They are clones
