58 generations of cloned mice from one donor collapse after 1,200 animals with success rate falling to 0.6% and final generation dying within one day
Researchers successfully cloned a single mouse and then repeatedly cloned its descendants for 58 generations over two decades, producing more than 1,200 animals from one original donor. Yet the experiment ultimately ended in failure when the entire lineage collapsed due to accumulating genetic damage. This visual powerfully captures the central message of the study — …
