In 2008 genetic analysis was carried out on the mummified remains of Tutankhamun and others thought or known to be New Kingdom royalty by a team from University of Cairo. The results indicated that his father was the KV55 mummy, identified as Akhenaten, and that his mother was the KV35 Younger Lady, who was found to be a full sister of her husband. This means that the KV35 Younger Lady cannot be identified as Nefertiti as she was not known to be a sister of Akhenaten. The team reported it was over 99. 99 percent certain that Amenhotep III was the father of the individual in KV55, who was in turn the father of Tutankhamun. The validity and reliability of the genetic data from mummified remains has been questioned due to possible degradation due to decay. Researchers such as Marc Gabolde and Aidan Dodson claim that Nefertiti was indeed Tutankhamun's mother. In this interpretation of the DNA results the genetic closeness is not due to a brother-sister pairing but the result of three generations of first cousin marriage, making Nefertiti a first cousin of Akhenaten.
