In the cloning of cattle, a fertilized egg is taken out of the mother's womb and:

1. the egg is divided into 4 pairs of cells which are implanted into the womb of other cows
2. in the eight-cell stage, cells are separated and cultured until small embryos are formed
which are implanted into the womb of other cows
3. in the eight-cell stage, the individual cells are separated under an electrical field for further
development in cultural media
4. from this, up to eight identical twins can be produced
