Five cloned monkeys created in China using the same technique that produced Dolly the sheep

Five cloned monkeys have been born with a host of genetic mental health conditions in a controversial experiment in China. The monkeys - all clones of one primate - have been specially bred to create a'diseased' population of animals to use in laboratory tests. All five have the same DNA altered, which has resulted in symptoms similar to the human conditions of anxiety, depression and schizophrenia. The quintet were born at the Institute of Neuroscience (ION) of the Chinese Academy of Sciences (CAS) in Shanghai. Researchers used the same technique as was used last year to produce Zhong Zhong and Hua Hua – the first ever two cloned monkeys - and Dolly the sheep, famously cloned in the late 90s in Scotland.
