Processes used to produce transgenic species Transgenic species are groups of organisms that contain genes from other species. Transgenic animal species are produced by two main methods: the transgene ("two separately cloned genes are spliced together, one gene contains the coding sequence for the protein of interest and the other controls the tissue in which the animal protein will be expressed") can be microinjected in or created by using embryonic stem cells. The microinjection method …showed first 75 words of 601 total…

Other transgenic animals such as pigs are bred to be leaner and grow faster, but this comes at the expense of them developing arthritis that makes them unable to stand. Furthermore, there is also the questioning of producing animals for xenotransplants for the purpose of being killed and used for transplant organs and tissues. However, the argument for this is that we already kill animals for the purpose of eating them.
