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.There are many benefits that come from the creation of genetically modified animals. For instance, by the manipulation of their genes, scientists are able to study the functions of genes, gene tic diseases and how to treat genetic mutations such as cancer and other illnesses. Most of these genetically modified animals are used for the economic production of food items that are rich in rare nut essential nutrients. Genetically modified animals are also created with the development of the medical sciences as well. For instance, some animals can be genetically manipulated to grow replacement organs and tissues for humans and to harvest other medically valuable components to battle certain diseases and in many cases .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 production. 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 modifi ed foods do the rest.

Due to the changes in climate, such as coldness, farmers are not able to do farming during certain periods of the year. Most of the foods do not tolerate extreme weather or climate changes, so as a result, crops may produce low volumes. In order to address this, genes of the plants that can withstand coldness have been added to the food producing plants, making the latter category more cold resistant. This is one of key benefits of genetically modified foods. As another benefits of genetically modified foods, in some other countries, paddy has been developed genetically where they can withstand low water supply. Water is one of the burning issues in some of the developing countries.
