Pros And Cons Of Artificial Selection

Improved Essays
PSS is not the only example of when artificial selection has gone wrong. There are many positives to artificial selection people just need to become educated and make sure they are not breeding for genes that can have adverse reactions, other than what was originally expected. This does raise the question of the ethics of artificial selection in relation to the quality of life the pigs will have living with the stress gene. Humans have been doing artificial selection for a long time with many successes and some failures. When working with live animals the mutations can become even more apparent in the behavior of the animal. With every success has to come some failures and as they are to be expected with any science. Mutations are very unpredictable …show more content…
This later changed with the introduction of Medellin genetics which allowed people to understand a little better the complex process of breeding livestock for desirable traits. Today, there is a lot more technology that can help a breeder to breed the livestock, helping to bring up another question. The other question is how we can or should look into animal welfare while artificially breeding. This is not occurring in the case of the PSS gene in show pigs as the pigs are living with a disease that causes them many anxieties throughout their life, and even rougher in their last minutes. With the invention of the artificial insemination (AI) rod natural breeding was no longer required making it easier for people to get the boar they want to breed with the sow they want. Some other points of interest include superovulation which is allowed several embryos/ eggs from a single donor, more than they would usually produce. Some people have gone so far as to start cloning animals like Dolly the sheep who was the first animal to be cloned from an adult. (Sandøe, P., Christiansen, S., & Gamborg, C. n.d). The further ethical implications of ignoring genetic diseases such as PSS are quite large and hard to comprehend. There are many times that humans inadvertently breed a bad thing in with a good gene. The only problem with that is that they do nothing to fix the issue, and just

    Some people believe that Animal experimentation has played a huge role in enabling people to discover, prevent and cure diseases. Many diseases were found and there were numerous advantageous results from the experiments. However, there is a problem with this reasoning because the drugs or medicine that are invented by animal experimentation can respond differently in humans. According to the statistics, 92 percent of all drugs that were guaranteed safe to be used for humans and that were effective in animals, failed in human bodies because they were dangerous and did not really work. ( Food and Drug Administration) Penicillin is a antibiotic agent which is commonly used in the treatment of bacterial infection.…

    Although animal testing saves many from having deadly side effects happen to them, it is unethical, and there are better ways to test these results. The lives of animals are taken each day due to unnecessary testing that can be performed in different ways. One could argue the practice of this is inaccurate, and there are multiple other ways for testing on things that would be more accurate and would not harm the animals. After all, animals and humans are two completely different species who react to conditions differently. Based on the traditional theorization that animals respond the same way humans do when exposed to certain products, mostly rabbits, mice, and rats, are subject to tests that determine the safety of cosmetic, personal care,…

    The Impacts of Modified Foods Genetically modified foods have an impact on everyone including animals. Anyone that is concerned with genetically modified foods shouldn’t worry. It mostly impacts humans in both good and bad ways, but mostly in a positive way. Many may agree that genetically modified foods are bad for anyone who eats it. Some will argue that we shouldn’t tamper with the organism, but we’ve been modifying organisms since the beginning of time.…

    Since Snuppy was the first dog to actually be cloned, this was heightened. There is another way in which this case was seen as beneficial, however it is perceived as slightly minor in regards to the other benefits. This application of cloning does not relate to dogs only, but to all animals which can be considered to be pets. Many who have mourned the loss of a pet have ‘brought it back to life’ through reproductive cloning. While this may seem a little extreme, this scientific breakthrough has made it possible for these pet owners to feel connected to their deceased pets once again.…

    The True Pain Of Safety Over many continents and through many time periods animal testing has had a strong presence in science. Many places and companies today have discontinued the use of animals due to its, at times, extremely inhumane practice. Though without the use of animals, many important discoveries, procedures, and vaccines wouldn’t have been found. Animal testing, though some has been found to be cruel, is a helpful tool for future discoveries, and should be continued today because of the usefulness in researching for the safety of humankind. According to Dictionary.com animal testing is, testing using a nonhuman subject for the safety sake of humans (The definition).…

    One may say that by the use of experimenting on animals have helped humans discover more about our bodies and how they function and react to different substances (Woods 8). Through animal testing we have found out about many vaccinations to help the health of the world. Some treatments they were founded through experiments were the polio vaccine, breast cancer, brain injury, childhood leukemia, tuberculosis and hepatitis B (Animal Testing). Through animal testing we have found out many great useful vaccinations to better our health and have learned more about the human body. Animal testing is not always the way to go.…

    Animal Testing Is Wrong

    Besides helping humans from the animal testing, the animals can also benefit. The American Veterinary Medical Association approves animal testing since, with some of the shots that are supposed to help humans, can also save their lives from rabies, leukemia, or tetanus (ProCon). It is very acceptable to experiment on animals because according to researchers, because the animals don’t have rights it is morally right to experiment on them (ProCon). With this stand, if animals were given rights than hunting would have to become outlawed, along with everybody having to become vegetarians (ProCon). Animals are treated really well or else the results will become unreliable and the entire testing process will have to be started over (ProCon).…

    Today there are many new types of tests. These tests could be more beneficial to new medications and cosmetics. Animals should not have to be put on the spot to save humans. Animals are capable of feeling and enduring as much pain as humans do! Why make them suffer for research that may not even work?…

    Do you think something as fictional as glow-in-the-dark animals or spider-goats is possible? Well, thanks to today science, animals can have extraordinary traits they wouldn’t normally show. Scientist have manipulated around with an organism’s genes for a while, this is known as genetic engineering (GE), and they can now transfer genes from one animal species to another. With GE animals, scientist can advance human health, food production, and other needs of people. These GE animals bring up a lot of concern among people about the well-being of the animals, so the U.S. Food and Drug Administration (FDA) regulates GE animals.…
