* Asexual reproduction: This is the most general term for any form of reproduction that doesn't involve the fusion of gametes (sex cells). Examples include budding, fission, and parthenogenesis.

* Self-fertilization: This is a specific form of sexual reproduction where an individual produces both male and female gametes and fertilizes itself. This is common in some plants and hermaphroditic animals.

* Clone: This refers to an organism that is genetically identical to its parent. Clones can be produced through asexual reproduction or through artificial means like cloning technology.

The most appropriate term depends on the specific type of reproduction you're interested in.
