Animal Cloning
Animal cloning is a procedure that involves creating a replica of an animal through asexual reproduction. This process makes a duplicate of genes and differences between cells and organs occur. In 1996, scientists from the Roslin Institute of Scotland caused uproar by successfully cloning the first animal from an adult cell. The main purpose of cloning is to produce healthier organs and maintain biodiversity; scientists want to make sure that the endangered species are preserved and protected. By doing so, they will be able to study these clones in order to have a broader knowledge on the development of the embryo

Because of this, damaged tissues and cells are replaced by genetically identical organs. Kidney and bone marrow transplant, for example, are benefits of cloning because it aids in supplying animals with the organs they would need. Also, through cloning, endangered species are protected from extinction. For example, Panda cells in China are produced to preserve their species. According to All About Animal Cloning (n.d.), animal cloning produces healthier offspring. This minimizes the use of antibiotics and the use of growth hormones on animals. Not only does animal cloning help animals but also humans. In March of 2000, the Roslin Institute (2014) explains that cloned pigs helped in supplying donor organs for xenotransplantation. This is the process of implanting animal organs into …show more content…
As stated by the University of Utah (2014), animal cloning results to abnormal gene patterns and genes are not expressed at the right time. In cloning, the nucleus is not arranged to reveal genes at a certain time as compared to the nucleus of a natural embryo. Scientists are the ones that arrange the nucleus and they reprogram it for the development of the animal. These scientists do not completely reprogram cloned animals which results to abnormal growth of the embryo. Aurelia (n.d.) explains that cloning creates identical genes and this prevents the process of replication. When that happens, genetic diversity gets hampered, which results in a decrease in the ability of animals to adjust. Aside from this, it also inflicts harm on the health and safety of organisms. University of Utah (2014) describes that animal cloning yield a high failure rate, in which only 0.1% to 3% of animal cloning succeeds. This implies that if animal cloning is done one thousand times, only thirty clones will be created while the other 970 do not make it. This occurs because the nucleus and surgically removed egg have the possibility of not being well matched. It is also because the transferred nucleus does not split up and grow efficiently. The Roslin Institute (2014) stated that before the Dolly was created, two hundred seventy-seven cell fusions had to happen. Twenty- nine embryos were used and inserted on thirteen proxy mothers and out of all
