Genetic engineering of animals: Ethical issues, including welfare concerns

Be it livestock or crops, the alteration of genes, for example to boost growth, could have side effects such as weakening resistance to a particular disease.

Genetic engineering is one of the topic that causes a lot of controversy. Scientists do not yet know absolutely everything about the way that the human body works although they do, of course, have a very good idea.

Studies have revealed that cloned mammals may suffer from developmental abnormalities, including extended gestation; large birth weight; inadequate placental formation; and histological effects in organs and tissues for example, kidneys, brain, cardiovascular system, and muscle.

However, one of the problems with changing the structure of human DNA, is the subsequent loss of natural variation. The contribution of genetically modified animal models. Many plants and animals form hybrids in nature. Wildlife conservation and reproductive cloning. March 15, ; [accessed March16, ].

Ethical and Social Issues "Playing God" has become a strong argument against genetic engineering. Tackling and Defeating Diseases Some of the most deadly and difficult diseases in the world, that have so resisted destruction, could be wiped out by the use of genetic engineering.

It should be noted that no matter what the application of genetically engineered animals, there are restrictions on the methods of their disposal once they have been euthanized. Wild animals The primary application of genetic engineering to wild species involves cloning.

Having a genetic screening with a fetus can allow for treatment of the unborn. Cloning Fact Sheet These interactions also vary with the genetic background of the animal, as has frequently been observed in genetically engineered mice With progress in genetic engineering techniques, new methods 3031 may substantially reduce the unpredictability of the location of gene insertion.

Pros and Cons of Genetic Engineering

What unintended personal, social, and cultural consequences could result? Effects on the Environment Although the positive impacts of this field could be enormous, there are many questions raised that needs to be answered. Hence a breed of pigs containing human elements in their DNA was created.

This is a clear indication that genetic engineering has the potential to improve the quality of life and allow for longer life span [ 2 ]. For meateaters, the same question could be posed about eating pork with human genes. This highlights the importance for veterinarians, as animal health experts, to be involved in the discussion.

Ethical Issues in Genetic Engineering and Transgenics

Other changes could result into the toxicity of an organism to humans or other organisms. For example, production costs can be lowered and health, taste and look of a product maximised.

Genetic Engineering Essay

In the National Academy of Sciences released a report calling for a legal ban on human cloning [ 11 ]. In the early stages of genetic engineering, the primary technology used was transgenesis, literally meaning the transfer of genetic material from one organism to another.

Animal integrity, animal dignity, and genetic engineering. A cat cloned by nuclear transplantation. British Medical Journal Vol. One pressing question and issue with genetic engineering that has been around for years and years is whether it could end up going too far. Until we as a society or, perhaps, as a global entity can agree on what beings—human or otherwise—are worthy of moral and legal status and respect, we can expect intense cross-disciplinary debate and discussion as new life forms are created through science and medicine.

Utilization of genetically altered animals in the pharmaceutical industry. Gene therapy is available only to the very rich and elite, which means that traits that tend to make people earn less money would eventually die out.

As more human genes are being used in non-human organisms to create new forms of life that are genetically partly human, new ethical questions arise.

Produce New Foods Genetic engineering is not just good for people. So if genetic engineering creates animals that help us to develop new human medicine then, ethically speaking, we may actually have a moral obligation to create and use them; or because of an expectation that genetic engineering of animals can help reduce experimental animal numbers, thus implementing the accepted Three Rs framework.

But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. Due to the high similarity in genetic sequences for proteins among species, transgenic organisms are able to effectively assimilate and express these trans-genes. Tissue engineering is becoming a viable alternative in procedures that involve replacement of cartilage, heart valves, cerebrospinal shunts, and other organs.

However, the greater variety of available applications, and the large numbers of animals required for the creation and maintenance of new genetically engineered strains indicate that there is still progress to be made in implementation of the Three Rs principle of Reduction in relation to the creation and use of genetically engineered animals Pros and Cons of Genetic Engineering ‘Genetic engineering’ is the process to alter the structure and nature of genes in human beings, animals or foods using techniques like molecular cloning and transformation.

Genetic engineering otherwise called genetic modification and can basically be described as the ‘direct manipulation of an organism’s genome’ which is the complete set of genetic material of an animal, plant or other living thing. Genetic engineering and transgenics continue to present intriguing and difficult challenges for 21st century scientists and ethicists, and education and meaningful, respectful discourse are just the beginning of what is required to tackle such complex ethical issues.

Human, Social, and Environmental Impacts of Human Genetic Engineering

Genetic engineering, the alteration and recombination of genetic material by technological means, resulting in transgenic organisms, can cause the eliminations of. Genetic Engineering ( words) Biology Also known as: biotechnology, gene splicing, Soon after the publication of the short essay by Crick and Watson on DNA structure The debate over the issues of “tinkering with God” heated up and public outcry.

engineering; and finally, issues of justice, especially fair access to genetic therapies and enhancements. Note that given the scope of this paper there are .
