In 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 electrical field for further

development in culture media

4. from this upto eight identical twins can be produced
