A two-decade study into cloning has revealed a fundamental flaw in the technology, demonstrating that repeated duplication ...

Cloning promises genetic copies, but a growing body of research across dogs, mice, cattle, and primates shows that clones begin diverging from their donors almost immediately. Thousands of unique ...

Revealing the limitations of cloning, researchers who repeatedly cloned mice for two decades have discovered that such serial duplication triggers grave genetic mutations that accumulate over the ...
