cloning doesn’t produce perfect copies, with big implications for farming and de-extinction efforts, discovers Michael Le Page A CLONE is meant to be a genetically identical copy, but an extraordinary 20-year study has shown that this isn’t the case. It reveals that clones have lots of extra mutations and, if you keep cloning clones, these build up to fatal levels. The findings have implications for the use of cloning in farming, efforts to recreate extinct species, and the potential use of cloning technology in people.
