Hi all

So are we now saying it's possible for a child to take a DNA test then their parents and then the results show no links between them  ???

Makes me think twice about getting my test done  ;)

That's what I have read.  Only 30 cases are recorded though.

But these cases are likely some (or all) of those which have gone to a Benefits / Paternity Appeal.

I wonder what the total of those who have been tested for this specific condition are?

Some more data would be interesting!

Rootschatter Guy Etchells, noted this lady with Genetic Chimera in a reply on another thread, but it didn't seem to get noticed.

1746, I just watched the program, and it was truly remarkable. Anyone with an interest in DNA should watch it. The link further up this thread should be watched from 15:30. It is truly remarkable.  The events of this article were reported by National Geographic Magazine 7 years ago.


Hello Martin and All

I couldn't believe what I was hearing, whilst at the same I'm recently being bombarded by adverts and emails to take various DNA Tests for family tracing purposes.

Hello

Thank you, interesting that link!

Yes, information says a Father too, can be affected by extra DNA.

His Child's DNA then shows no match to his DNA.

Claims of other transfer too.

Good job I applied for yet another Will (looking at the notebooks it must be over 100 Wills seen, trying to make an ancestor link)  ???

Genetically is showed the father as the child's uncle and presumably this would also be the case for a women and the child would show as the mothers niece/nephew.  In the Fairchild case the grandmother still tested as genetically the children's grandmother!
Nobody can really know how prevalent genetic chimerism without more DNA testing.

How often in real life do we know of examples where the child is the offspring of an uncle or where grandpa is the daddy and everyone involved goes into denial?  With as common as the problem is, I think I'd believe the DNA test as people do have reasons to lie.
