As someone who pirated lots of floppy disks and cassettes in my day, I'm not suprised.

I can't believe the mouse turned into a sheep after 58 clones

Wow, biologists discovered the point when they need to stop cloning from the original long before Hollywood producers did.

In the 1970's my mom predicted about 60 generations to total failure due to replica fading. She was a cellular biologist and had noticed patterns.

Star Trek: The Next Generation, season 2, episode 18. Up the Long Ladder. Dr. Polaski identified this very problem on a planet full of cloned survivors in a colony on a planet which was composed of clones of the 5 survivors of the ship that crashed there hundreds of years earlier. It's called "replicative fading".

My neighbors cloned their dog. Version two was an absolute nightmare that hated them. Whatever controls personality didn’t seem to like being copied.

I think it's interesting all these scifi episodes where they dabbled with the subject turned out to be closer to the truth than the suspected theory of that time.

I recall hearing something 30 or 40 years ago about plants being limited to about 50 'generations', so the mice failing at 58 clonings doesn't surprise me a whole lot.

This is the most interesting video I've watched on cloning in a long, long time.
