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

  1. A
    the egg is divided into 4 pairs of cells which are implanted into the womb of other cows
  2. B
    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. C
    in the eight cell stage the individual cells are separated under electrical field for further development in culture media
  4. D
    from this upto eight identical twins can be produced

Solution & Step-by-step Explanation

In embryo splitting (a form of cloning), an embryo at the 8-16 cell stage is divided into individual cells or groups of cells. These are then cultured to develop into multiple identical embryos, which are subsequently implanted into surrogate mothers (cows).
