    1. a cell is removed from the mammary gland of the DNA donor sheep - donating its DNA to the recipient sheep and give characteristics
  • 2. an egg is removed from egg donor sheep - the nucleus is removed to form a de-nucleated egg
  • the de-nucleated egg and the donated DNA are fused together using an electric shock
  • the fused cell is given another electric shock to divide and form an embryo
  • the embryo is implanted into the uterus of a surrogate sheep
  • cloned animals have identical genes so they will be genetically identical, but not necessarily phenotypically identical due to environmental factors
  • the surrogate sheep gives birth to a lamb which is a clone of the DNA donor sheep
