Mammal Cloning Hits a Genetic Wall After 58 Generations
Scientists have successfully cloned a mouse for two decades, but their latest experiment has revealed a genetic ‘dead end’ to mammal cloning. Researchers in Japan created over 1,200 mice from a single original donor by serially cloning and re-cloning the animals for 57 generations. However, the team discovered that the mice accumulated so many genetic … Read more
