Cloning Animals

To clone animals, we use two primary methods:

Embryo transplants

  • Developing embryos can be split into smaller groups of cells before differentiation (cell specialisation) to give many smaller and identical embryos, which can then be put into host mothers.
  • A classic example would be a farmer fertilising egg cells produced by his best cow with sperm taken from his prize bull. The farmer would then split the resulting embryo and implant the clones into the uteruses/wombs of other cows.

Adult cell cloning

  • The process of adult cell cloning is:
    • Take an unfertilised egg cell and remove the nucleus.
    • The egg cell is then injected with the nucleus from an adult body cell, belonging to the animal which is to be cloned.
    • An electric shock is given to the egg cell to stimulate it to divide.
    • Once the embryo has grown into a larger ball of cells, it is implanted into a surrogate mother.
    • The embryo (a clone of the original adult body cell) will continue to develop in the womb of the surrogate.
