Disadvantages Of Transgenic Animals

Transgenic animals are animals that have had foreign genes inserted into their genome so that they can reproduce genetically modified children. Such animals are most commonly created by the micro-injection of DNA into the pro nuclei of a fertilized egg which is subsequently implanted into the oviduct of a pregnant surrogate mother. This results in the animal giving birth to genetically modified offspring. They are then bred with other transgenic offspring to establish a transgenic line. Transgenic animals are used in the labs as models in biomedical research and are tested on in many different ways they are testing many things on different animals such as too see if transgenic chickens will grow bigger and faster than other normal chicken’s and too see if transgenic sheep will grow larger and produce more wool, they trying to create better and stronger animals.
Transgenic organisms have also been developed for commercial purposes. Food crops like soy and corn that have been genetically modified that are resistant to pests and herbicides. These crops are widely known as genetically modified organisms and are the next big thing because they are resistant’s against pests and are cheaper to

DNA is introduced using recombinant DNA technology that is transmitted through the germ line so that every cell of the animal contains the same identical modified genetic material. To improve livestock that are larger and leaner and grow faster and are more efficient when comes too feeding them and the livestock are also more productive and more resistant to disease. Pharmaceutical products are tested on many different animals such as mice and rabbit, sheep and cattle. Pharmaceutical products can now be made using transgenic animals such as growth hormones and insulin for diabetes treatment. Cows produce insulin in their milk so that can be used to treat
