WolfishMusings- Bone marrow recipients for the rest of their lives have the DNA of their donor rather than their own in their blood. The rest of their body continues to have their own DNA, as would be expected. This actually complicated a criminal investigation a few years ago. I was thinking more along the lines of chimeras, which it’s unknown how many there are. Since there are almost no symptoms, most people with more than one set of DNA will never find out about it. I mentioned previously the case of Karen Keegan who was told that genetically her children were not hers until it was found that she was a chimera and didn’t know about it. Yes, this is very rare. To be matir a mamzer though, you go to great lengths.
