Here's a breakdown of the term:

* Clone: A genetically identical copy of an organism. This can be achieved through various techniques like:

* Asexual reproduction: Many plants and some animals can naturally produce clones through methods like budding, fragmentation, or parthenogenesis.

* Somatic cell nuclear transfer (SCNT): This is the process used to create Dolly the sheep, where the nucleus of a somatic cell is transferred into an enucleated egg cell.

* Artificial embryo twinning: This involves splitting an early-stage embryo into two or more parts, each of which can develop into a separate individual.
