Japanese Researchers Make 581 Copies of Same Mouse through 25-Rounds of Cloning

Japanese researchers have successfully made 581 exact genetic copies of one mouse after 25 rounds of cloning. They say that these "perfectly cloned mice could pave the way for milk and meat from 'super' animals created in the lab."

According to Doctor Teruhiko Wakayama: This technique could be very useful for the large scale production of superior quality animals, for farming or conservation purposes. The rodents live a normal lifespan and the process can be carried on indefinitely through successive generations. The cloned mice showed no signs of growing old prematurely and appeared mentally and physically perfect."
