1) Two embryos are fertilised with sperm creating an embryo from the intended parents and another from the donors.
2) The pronuclei, which contain genetic information, are removed from both embryos but only the parents' is kept
3) A healthy embryo is created by adding the parents' pronuclei to the donor embryo, which is finally implanted into the womb

Step 2. The majority of the genetic material is removed from both eggs. :cool:
Step 3. The mother's genetic material is inserted into the donor egg, which can be fertilised by sperm
