The cloning is a method that manages to create an organism that is the exact same copy of the organism from which the genetic material have been acquired. So we have a situation where the parent and the clone have the exact same genes, which results in totally same physical appearance, and most often in same behavior.
It has been over half a century now since the first cloning took place, and the advancements in the genealogy have contributed to constant improvement of this method, so much so that nowadays it is even considered to resurrect some species that have been extinct for thousands of years.
