The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the first successful animal clone of a sheep, "Dolly."
Cloning refers to copying genes and other pieces of chromosomes to generate enough identical material for further study. Two other types of cloning
produce complete, genetically identical animals. Blastomere separation (sometimes called "twinning" after the naturally occurring process that creates identical twins) involves splitting a developing embryo soon after fertilization of the egg by a sperm (sexual reproduction) to give rise to two or more embryos. The resulting organisms are identical twins (clones) containing DNA from both the mother and the father. Dolly, on the other hand, is the result of another type of cloning that produces an animal carrying the DNA of only one parent. Using somatic cell nuclear transfer, scientists transferred genetic material from the nucleus of an adult sheep's udder cell to an egg whose nucleus, and thus its genetic material, had been removed. (All cells that are not egg or sperm cells are somatic cells.) One goal of this and similar research is to develop efficient ways to alter animals genetically and reproduce them reliably. Alterations have i
People may just treat them as pets or something lesser than sentient beings. Also if there does happen to be human clones then it would cost too much to get organs from a clone when you must try about 18 times to get a good enough clone. For centuries, black people have been the victims of racism and injustice. The argument about the casualties along the way is the most persuasive however. A clone is really just an identical twin of the original person, and identical twins already exist in the world and do not appear to have overly destroyed human uniqueness. Zavos and Antinori say that helping these couples is the goal of their research. Many people are against cloning because they feel that cloning is as much moral problem as a technical problem. One potential use of cloning technology would involve creating a human repair kit. When you make a clone you are creating just another living and thinking human. The group said that the procedure would involve injecting cells from an infertile male into an egg, which would be inserted into the female's uterus. In anuary 2001, the British government passed rules to allow cloning of human embryos to combat diseases such as Parkinson's and Alzheimer's. And one can surely imagine clones being created who are not abused in any way. But people can and have treated others as property, we call it "slavery" ,for years, and to date none of the slaves have been clones.
