Ralph was the first cloned rat. To give birth to Ralph, 129 embryos were implanted into 2 females. One became pregnant and gave birth to three rats; Ralph was the first to be born. Ralph has been cloned for medical purposes requiring genetically identical animals including testing in impact of genetics and the environment in the development of many diseases, as well as to take away and modify genes,[2] as well as to solve a problem with rat physiology.[3] Cloned from an adult cell, Ralph was cloned by researchers from China and France.[4]
