  • 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.
