| 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 |
