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.Farmers who grow genetically engineered food are greatly benefitted by their added qualities. Some genetically engineered food crops are modified to be able to withstand certain herbicides so that the farmers are able to use them liberally to get rid of weeds while others are created with built in pesticides that repel bugs and other pests. Other genetically engineered food is created with long life and resilience to adverse weather conditions in mind. For instance, some species of corns are created to withstand the harsh chill of winter and to keep them from rotting in heavy rains. Other species such as tomatoes which are one of the first vegetables to be engineered are modified to have a more vibrant colour, better taste and much longer shelf life and even .Apart from aiding the development of the medical sciences genetically modified animals are also taking the food and farming industry by storm. For instance, cows can be enhanced to produce more milk, pigs to create leaner bacon and sheep that are able to produce larger quantities of wool. These genetic modifying techniques can also be used effectively to create animals that are resilient to certain diseases that can pass on to humans.

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 characteristics. 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 coul d pose a threat to mankind
