The creation of genetically modified animals the altering of an animal?s genetic codes to make sure that it displays only the expected characteristics and do not possess any undesirable qualities. This is done by the addition of genes from other species, the deletion of undesirable genes or modifying the existing genes to bring certain traits forward. Though chimeras and cross breeds have been pretty much a staple in science fiction novels, nowadays, it is a wide known fact. The popular techniques to create genetically modified animals include pro-nuclear micro-injection, embryonic stem-cell manipulation and nuclear transfer. Genetically modified animals such as rabbits, cows, goats, pigs, rats, mice and cats are created with these techniques to arm them to serve their expected purposes.Pest resistance is one of the prominent benefits of genetically modified foods. Due to insects and pests, farmers lose a lot of money and lose a lot of crop globally. The aggregated loss is gi gantic when it comes to the global level. Therefore, the genetically modified foods were introduced with the characteristics of pest resistance. As an example, some plants and flowers are pest resistant by nature. The scientists have taken the gene responsible for making such plants pest resistant and have added it to the foods we eat. Then the foods get the pest resistant ability, while producing more crops. In addition to that, the farmer is at advantage as he / she does not have to spend on chemicals and mechanisms for pest control. On the other hand, the consumers receive clean and healthy foods that have not been in touch with deadly chemicals and even Organic to go food corporation.The tolerance of herbicide is one of other benefits of genetically modified foods. Usually, the crops are sensitive for the other weeds in the field and due to the same, crop would produce less amount of pr oduction. In the conventional method, the farmer will have to spray chemicals in order to control the weeds, a few times. With benefits of genetically modified foods, farmer will have to use chemicals only one time and the benefits of genetically modified foods do the rest.
Though genetic engineering techniques such as gene splicing of different species or cloning are generally frowned upon by the public as unethical practices that are against the rules of nature, these very procedures can save certain animals from going extinct and from becoming endangered due to manmade effects. The main dangers associated with genetically modified animals and the techniques used to create them are the risks of misuse and the disruption of natural genetic information. Since most modified farm animals are released out to nature, a lot of people are worried that they may cause disruption to the eco system and the delicate balance of nature with their un-naturally enhanced characterist ics. It is considered that with the large amount of genetically modified animals and plants in the world today could lead to the acceleration of genetic erosion, harmful and dangerous mutations as well as the creation of all new diseases that could pose a threat to mankind
