If two eggs are released by the mother's ovaries and both are fertilised, two foetuses develop with Separate placentas. These are called eternal twins. Identical twins come from the same egg and sperm, and so have exactly the same genes. The single fertilised egg splits at an early stage, producing two foetuses that can grow into identical twins
