Human cloning: a blessing or a curse
...ssed doubt about his plan. Dr Wilnut works at Edinburgh’s Roslin institute in Scotland, the “ hometown” of the cloned sheep, Dolly, said Antinori’s experiment could hardly yield satisfactory result. Because many animal cloning experiments had shown that very few cloned animal embryos survived to birth, and many of these died shortly after, also survivors were often grotesquely large or had defects. He thought that the same facts would be true of human embryos. Although Antinori and Panos announced that they can screen cloned embryos for defects, therefore defective embryos will not be implanted. Dr Wilnut disagree with it, he claimed that no clinic can screen all of an embryo’s genes for problems. We known that a normal child has a 50-50 mix of its father and mother’s genes, prepared for their embryonic role in eggs and sperm over months and years. In contrast, in cloning the genes are almost entirely from one parent, the calibration of genes is just done in minutes. Moreover, Dr wilmut said cloning a human would be extremely cruel. He pointed out in his experiment a cloned lamb hyperventil...
