* Commonly used in mice to propagate required characteristics.
* '''Embryonic stem cells''' are used as a source of '''totipotent nuclei''', which are capable of dividing into a range of new cells.
* These cells are fused with pre-ovulatory oocytes which have had their own haploid nucleus removed using electrofusion.
* Cells are artificially stimulated to the second meiotic division and begin embryonic development.
* The cell source ,capable of replication in culture, can be stored by freezing and is therefore 'immortal' and able to produce many identical individuals.
* Cloned individuals have a high percentage of developmental abnormalities.
** Often associated with Arthritis and Joint problems.
