>>16247140That's not what happened at all, you bumblefuck.
To this day Mew remains the only one of its kind.
In the time when the pokemon games were released there was a lot of controversy on the cloning front.
With the first successful cloning of a live specimen ever, the sheep Dolly, it gained significant world wide attention.
The method of cloning used was to imprint the DNA of the donor to the unfertilized egg of a female of the same species and have the female give birth to the clone.
That is exactly what happened in the games too.
In game canon Mew gave birth to Mewtwo, she is his mother and Mewtwo is an enhanced, radically altered clone of Mew.
