Dna experiments on human embryos are unethical and should not be allowed
The resulting embryos would be kept for up to 14 days to harvest stem cells.In the present state of science, hybrid embryos are produced as research tools, and only kept alive for 14 days or fewer. The article below only deals with the ethical issues of this case, and not with the ethics of producing new creatures that are a combination of animal and human.A hybrid embryo is a mixture of both human and animal tissue.

In early 2000, an Italian and a U.S. scientist announced their dna experiments on human embryos are unethical and should not be allowed to clone human babies for infertile couples. The duo recently announced their plans to begin implanting cloned human embryos into women-a step they may have already taken by the time this article is published. Rumors about the experiment had been circulating for weeks, prompting calls for oversight and even a moratorium on such work. The reason for the controversy stems from the nature of germline modifications, which differ from somatic gene therapies in a very fundamental way.
Unlike the latter, germline gene therapies are genome-editing techniques that affect egg and sperm cells, which means that patients with modified germ cells can pass them down down to the next generation. The researchers say that their results reveal serioHuman cloning is the creation of a human being whose genetic dna experiments on human embryos are unethical and should not be allowed is nearly identical 1 to that of a currently or previously existing individual. Recent developments in animal cloning coupled with advances in human embryonic stem cell research have heightened the need for legislation on this issue.
Despite their nearly identical titles, the two bills currently being considered by Congress call for markedly different policies on this critical issue. This latter type of cloning involves the creation and subsequent destruction of a clonal human embryo for the purposes of scientific or medical research. 2 Such embryonic destruScientists in China have genetically modified human embryos in a world first that has re-ignited the debate over the ethics and safety of genetic therapies that have the potential to prevent inherited diseases.The work raises fresh questions over whether restrictions should be placed on a new wave of genetic techniques that are rapidly gaining ground in labs across the world.The Chinese group used a genome editing procedure called Crispr to modify an aberrant gene that causes beta-thalassaemia, a life-threatening blood disorder, in faulty IVF embryos obtained from local fertility clinics.The embryos used for their experiments were abnormal and incapable of developing into healthy babies and would have been destroyed by the clinics.
They were not implanted into women once the modifications were made.The team, led by Junjiu Huang at Sun Yat-sen University in Guangzhou, is the first to publ.
