Andie Bynres found a story online which claims that scientists in Switzerland have analysed Tutankhamun's Y-chromosome and determined his haplogroup to be R1b1a2. The story is bouncing around several fora and blogs but the source is hard to determine. This article others rather more information and claims that the scientists have also analysed KV55 (they say Akhenaten so lets translate that back into a mummy and avoid the identification wit Akhenaten) and Amenhotep III. The scientists work for the Zurich-based DNA genealogy center, iGENEA.
That's when the story gets murky, because their website not only will sell you a test to see if you too are related to King Tutankhamun, they state:
So this is not new work on the official raw data. There are two problems with working from the Discovery Channel videos. The first is that the team which analysed Tutankhamun's DNA for publication in JAMA have stated that the first lab sequences were shot in the lab. However, it was taking them a week to re-sterilise the lab to resume work so TV crews were banned and much of the lab sequences were reconstructions. Now we know that, using the TV footage has to carry a warning that the results shown on TV may not be real - and so far as the Y chromosome is concerned could for instance by a reconstruction using the DNA of one of the scientists himself. Even if the footage was accurate, there is concern among geneticists that the results were contaminated and the methodology of the original study uncertain.In the year 2009 extended DNA-tests had been carried out with the mummy of Tutankamun and other members for his family. These have only partially been published in February 2010. Despite several demands, the results of the Y-DNA tests have been shut away.iGENEA was able to reconstruct the Y-DNA profile of Tutankhamun, his father Akhenaten and his grandfather Amenhotep III with the help of a recording of the Discovery Channel.
Putting the two together, with suitable caveats the data is probably useful to indicate familial relationships. I don't however feel comfortable myself with claims of a European haplogroup in such circumstances. It's possible, but the chance that it is a spurious result from a dramatised reconstruction seems very real to me.
We go back to wishing that the raw data had been fully published and then such stories wouldn't arise.
