Didn't know this was possible. You'd think a chimerical fetus wouldn't be viable. Immune system attacking body parts, that sort of thing.

I don't know if this is possible, or a hoax. But I am pretty sure that the immune system would not be a problem, as early fetuses exposed to foreign matter while their immune systems are being built, do not reject the foreign matter, but see it as "self."

Almost all of these fused embryos would result in a miscarriage. It would be very rare for the DNA to be compatible. Even more rare for it to be found.

How many men have been told they were not the father because of this condition? The world may never know.....
