The exact reproduction of an individual from cellular tissue is called cloning.
Cloning is a scientific technique that is used to produce identical copies of an individual having similar genetic information.
In this process, a complete cell, tissue, gene, even an entire organism can be cloned. 
A clone can be produced either by artificial or natural methods.
In nature, some unicellular organisms such as bacteria produce multiple copies of themselves by means of asexual reproduction.
The first ever human clone was named Eve in December 2002.
