cloning
...d then be replaced by the genetic material taken from one of the father's cells - perhaps a skin cell. A trigger would be applied to the egg cell that would then make it start to divide like any normal embryo. The mother would have it implanted in her womb in a procedure which is routinely performed in IVF clinics. The vast majority of pregnancies involving clones have gone very badly. In most of them, the clone has died and in almost all of them the lives of the mother and clone have been put at risk. In many cases, the clone grows abnormally large, often threatening to tear the womb that can also become swollen with fluid. Almost all clone pregnancies spontaneously abort. Of the small number (little more than 1%) of animal clones that make it to term, most have severe abnormalities: malfunctioning livers, abnormal blood vessels and heart problems, underdeveloped lungs, diabetes, immune system deficiencies and possibly hidden genetic defects. Several cow clones had head deformities - none survived very long. If a successful clone were to happen, the clone would be 99.9% identical to its parent. It would not be a complete copy because there are some important genes that would be contributed by the egg donor. These genes reside outside the nucleus. Also, the clone would be subject to different environmental factors and a different upbringing to his/her genetic parent. This could result in a changed app...
