Transgenic Animals
Much speculation exists regarding the ever-broadening technology of creating Transgenic Animals and their theorised suffering sparking a social, ethical and economic debate over cost factors of the research and development versus ultimate benefit to science aiding the benefit of our Society. Though one could persuasively argue for the benefits or risks of this process, this essay will demonstrate the future and present benefits and risks (ethical, social and economic) of this gene technology and evaluate how these advantages and disadvantages take part in human everyday life.
Clinton and Richmond’s (2009) publication defines Transgenic Animals as those animals that have had their genome altered deliberately to help

For example, Transpharmers that are engineered to produce life saving drugs in their milk and do not appear to suffer ill health effects. From the research, Transpharmers do not need to be sacrificed to obtain the medical benefit, they only need to be milked and thus the benefit to the society does not result in the death of the animal. Another ethically justified example is the Alzheimer’s mouse. It helps present symptoms of the Alzheimer’s disease by over expressing amyloid precursor protein which allows the build up in the brain of amyloid plaques consisting of toxic B-amyloid which mimics human Alzheimer’s disease (Games et al., 1995). The writer agrees with Games et al (1995) the construction of a disease model for this disease aids our understanding of Alzheimer and serves as a model for testing new therapeutic drugs which is a benefit to our society.
Due to complexities of intended use some experiments fall into ethically gray area in the writer’s opinion. For example, the Xenotransplanter pig. This animal has been reportedly genetically altered to not express specific genetic expressions that are viewed as foreign by the human immune system. The sector refers to this type of animal as a ‘knockout transgenic’ (Clinton, 2009) because the genetic alteration deletes the expression of the animal’s own gene instead of expressing a foreign human gene. Pig physiology has an enormous potential for
