Negative Effects of Animal Cloning
A method used to produce multiple copies of a certain animal is referred to as animal cloning. The most frequently and latest method of cloning is called Somatic Cell Nuclear Transfer. In this method, the nucleus is removed from one animal and replaced with a nucleus from the animal to be cloned Panno, 2009.
In most cases, the donor has to be an animal which has desirable traits. The cell will develop into an embryo that will be implanted into the surrogate mother. The born animal will have the same DNA as that of the donor animal, which will ensure that it will also have the same desirable traits.
Less biodiversity
Due to cloning and using of animals with the desirable traits, there is a likelihood that the animals cloned will all have the same DNA which will result in no biodiversity. This will mean that in case one animal is affected by a certain disease, there is a high chance that all the other cloned animals will be infected too. There are other far reaching consequences to this like a whole population of animals can be wiped out because of a particular disease. This will affect the whole food chain for other animals as well.
The lack of diversity in animals would lead to the weakening of the animals' ability for adaptation. Since cloning will use the DNA of certain animals, the resultant clones would not be able to adapt to environmental changes. Without diversity, the population of animals will not manage to adapt in order for its survival. As cloned animals will mostly have the same gene pool, there will not be any variable traits that would allow the cloned animals to adapt. Genetic diversity allows a species to evolve. Cloned animals will have less genetic variations and...
"Animals that are experiencing dwindling numbers could be cloned to prevent their extinction. Taiwanese scientists claimed to have made five clones of an endangered pig to save this species" (Anonymous). While some say man should not play God there are others like Edmund Erde who disagree and say that "playing God" is a phrase that is "muddle-headed" and "nonsensical" and should be deserted (Edmund Erde, p.594). For those who
Cloning is among the feats in science that many of us, as part of our childish character, ideas, and imaginations, have only visualized before. We used to say in our mind, "what would happen if we create someone who is an exact duplicate of ourselves?" Again we say, "how convenient it would be to have that someone do the things we don't want to do." Or, "have that someone face the
Mammals Cloning to Preserve the Endangered Giant Panda Among animals, mammals account for more than 15,000 species of vertebrate animals that have the ability to self-regulate their body temperature, have hair, and, in the females, produce milk. In the study of mammalogy, the branch of science that deals with mammals, there has been a growing concern at the rate of mammalian species nearing extinction. Thus, the Endangered Species Act of 1973 was
Human Cloning Should Be Illegal? Human cloning definitely brings negative effects to our society on value of life, economics natural resources and a multitude of other factors. Therefore, government should not legalize human cloning. The birth of a cloned sheep, known as Dolly has generated a great sensation around the world, ever since March 1997. Irrespective of the fact that it was not the first time that the experimentation for the
Human Cloning The subject of human cloning was once the stuff of science fiction novels and television programs. As technology and science improves, the creation of clones has become, potentially, a real likelihood in the impending future. For the follow, the definition of human cloning is that which has been designated by the American Medical Association: The term "cloning" will refer to the production of genetically identical organisms via somatic cell nuclear
Christian Biotechnology: Not a Contradiction in Terms Presented with the idea of "Bioethics" most people in the scientific community today immediately get the impression of repressive, Luddite forces wishing to stifle research and advancement in the name of morality and God. Unfortunately, this stereotype too often holds true. If one looks over the many independent sites on the Internet regarding bioethics, reads popular magazines and publications, or browses library shelves for
