r were frogs. This is because they have large egg cells and scientists can obtain up to two thousand of them from one ovulation. (McKinnel 79) Successful cloning has occurred with livestock. The drive toward success is not because livestock like cows and sheep are model organisms. Instead, the farming industry has made and continues to make a big effort toward finding a way to implement the technique of nuclear transfer for livestock. Research in cloning is also occurring in primates. The reason for studying primates is the similarities with humans. This leads us to the most talked about aspects of cloning, the use of the techniques with human cells and eggs. Cloning of humans in a biological sense already has and is occurring. Scientists are researching by splitting embryos to execute experiments to find data relating to cell differentiation, the use of stem cells, and genetic screening. Amazingly, genetic screening is occurring in Britain quite often. Fertility clinics aim this service toward couples where the mother or father has a genetic disorder. A fertility clinic will clone an embryo, then test it for genetic disorders. If the embryo tests negative for genetic disorders, then the fertility clinic implants a clone of that embryo. This should guarantee that the child would not have any genetic disorders. (Benoit 2) Amazingly, the first attempts at artificial cloning were as early as the beginning of this century. Adolph Eduard Driesch allowed the eggs of a sea urchin develop into the two-blastomere stage. Then he separated it by shaking it in a flask and allowing them to grow. The cells developed int...
