The disadvantages of cloning is that the beef could become toxic if it is cloned incorrectly. Human cloning would allow such parents to have a twin of their lost baby, but it would be like other twins, a unique individual and not a carbon copy of the child that was lost under heartbreaking circumstances. The ethical, spiritual, and scientific implications of such science creates a slippery slope for society. When many clones are produced, the desired gene is transferred into the human body through some vectors. They transferred the resulting embryo into the uterus of a surrogate ewe and approximately five months later Dolly was born. The primary biomedical benefits of cloning stem more from the use of this technology in the genetic modification of animals rather than from making identical copies, however.
In a nutshell, cloning can help facilitate the production of more farm animals which are genetically engineered for pharmaceutical and medical purposes such as xenotransplant organ procedures. Those whose motives arise from benevolence--for example, those who want to raise a child but have no other means of bearing a genetically related baby--should be allowed to undergo a cloning procedure. Using cloning techniques, the egg of the woman is taken out of the womb; it is fertilized with a foreign sperm. Cloning for research and therapy requires a large number of high-quality donor oocytes. The debate on human reproductive cloning seems to have drawn to a close. Many claim that it is morally wrong to manipulate nature. But suppose some people create a clone for instrumental reasons, for example, as a stem cell donor for a sick sibling.
The idea behind the cloning technique is that each of the cells in an individual contains the same set of genes and, under the right conditions, should be capable of directing the development of a new genetically identical copy of the original animal. It is one of the most serious problems faced in transplant surgery. The distribution of X inactivation, which seems to occur randomly, determines the appearance of the cat's coat. The taxation on planetary food supplies would be immense. This process occurs naturally with identical twins. Cloning is the process of making an identical copy of something. Development Of New Diseases By bringing in an entirely new group of people, that we have no experience or research on, we could be introducing many things into the human race.
Many countries or jurisdictions have legally banned human cloning or are in the process of doing so. The graft is then rejected by the body's defense mechanisms and destroyed, just as if it were a disease-causing organism. In 2002, Clonaid, part of a religious group that believes humans were created by extraterrestrials, held a news conference to announce the birth of what it claimed to be the first cloned human, a girl named Eve. Here are additional advantages and disadvantages of cloning animals to consider. What follows is an outline of some of the main areas of concern and disagreement about human reproductive cloning. Cloning mammals using embryonic cells has been successful since the mid-1980s for a history of cloning, see Wilmut et al. This 12-member Advisory Committee on Human Cloning convened five public meetings, each focusing on a particular aspect of human cloning: e.
Critics of this argument have pointed out that parents have children for all kinds of instrumental reasons, including the benefit for the husband-wife relationship, continuity of the family name, and the economic and psychological benefits children provide when their parents become old Harris 2004, 41—2, Pence 1998. These techniques are integral to the production of breakthrough medicines, diagnostics and vaccines to treat many diseases. Many readers have asked variants on this question. While this is helpful for curing people of potentially deadly diseases, it also could lead to the development of designer humans. She represented a first undesirable and dangerous step to applying reproductive cloning in humans, something that many agreed should never be done. Ever since Ian Wilmut and his co-workers completed the successful cloning of an adult sheep named Dolly, there has been an ongoing debate on whether it is right or wrong to continue 921 Words 4 Pages Human cloning involves removing the nucleus of a human egg and replacing it with the nucleus of an existing person Glannon, p. Stem cells obtained from that embryo would thus also be genetically identical to the patient, as would be their derivatives, and would be less likely to be rejected after transplantation.
Some authors have argued that a regulated market in oocytes could minimize ethical concerns raised by the commercialization of oocytes and could be consistent with respect for women Resnik 2001; Gruen 2007. This has been raised by opposing groups who see this as a threat to biodiversity. The mammary gland is a magnificent protein-manufacturing organ, and it also provides a convenient delivery system. Those whose motives arise more from narcissistic considerations -- people who want immortality or novelty -- should be prohibited from using the technology. Among the most pressing ethical issues raised by participating in such donation is what model of informed consent should be applied.
Genetic illnesses are not a leading killer of people today, but they could be in the near future. They decide not to have any more children. Both cell types have the ability to proliferate indefinitely and some studies show that after 60 cycles of cell division, stem cells can accumulate mutations that could lead to cancer. If poorly supervised or implemented without good intent, it could also be a scientific process that could harm our very future. According to Brock, it is not clear why this should be different in the case of cloning. Whether it be what race you, what language you speak, or how much money you make, prejudice and discrimination exists. That, she argued, would cut out the more serendipitous and sometimes more altruistic approaches of academic research.
Oocyte donation involves various risks and discomforts for a review of the risks, see Committee on Assessing the Medical Risks of Human Oocyte Donation for Stem Cell Research , 2007. Apart from the question of how slippery the slope might be, another question raised by such arguments concerns the feared development —reproductive cloning— and whether it is really ethically objectionable. If done successfully on animals, scientists and mankind might be looking at a future where stem cells in humans can be cloned to produce identical stem cells for specific people for future use. Parents would clone their existing child so that the clone can serve as an organ bank for that child, or would clone their deceased child to have a replacement child. Another potential problem centers on the relative age of the cloned cell's chromosomes. This young animal is referred to as a clone.
This is a controversial view. Although clones share the same genetic material, the environment also plays a big role in how an organism turns out. Born in 1996, Dolly basically had three mothers. The genes of these traits could be inserted into the embryo to ensure that they have them. Mitochondria are organelles that serve as power sources to the cell. Compensating A Loss Parents who have lost a child could clone them and have their child back. In the end, legalizing cloning on a wide-scale basis could lead to a disrespect for human life and the individual worth of a person, which might ultimately diminish all humans in the end.
What Are The Three Cloning Methods? The legislature plans to take up this discussion after January. This results to a significant difference on the cell makeup between the replicated and original organ. Only a small minority thought it was permissible, or even morally obligatory to conduct further research into human reproductive cloning. The animal with the copied material is the one which is referred to as a clone. It is the reproductive cloning process which produces a genetically identical animal.
