him as a son of Akhenaten's father, Amenhotep III, but that is only possible if Akhenaten's 17-year reign included a long co-regency with his father, a possibility that many Egyptologists once supported but is now being abandoned. While some suggestions have been made that Tutankhamun's mother was Meketaten, the second daughter of Akhenaten and Nefertiti, based on a relief from the Royal Tomb at Amarna, this possibility has been deemed unlikely given that she was about 10 years old at the time of her death. Another interpretation of the relief names Nefertiti as his mother. Meritaten has also been put forward as his mother based on a re-examination of a box lid and coronation tunic found in his tomb. Tutankhamun was wet nursed by a woman named Maia, known from her tomb at Saqqara. 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 mummy from tomb KV55, identified as Akhenaten, and that his mother was the mummy from tomb KV35, known as the "Younger Lady", who was found to be a full sister of her husband. 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. More recent genetic analysis, published in 2020, revealed Tutankhamun had the haplogroups YDNA R1b, which originated in Europe and which today makes up 50–90% of the genetic pool of modern western Europeans, and mtDNA K, which originated in the Near East. He shares this Y-haplogroup with his father, the KV55 mummy (Akhenaten), and grandfather, Amenhotep III, and his mtDNA haplogroup with his mother, The Younger Lady, his grandmother, Tiye, and his great-grandmother, Thuya, upholding the results of the earlier genetic study. The profiles for Tutankhamun and Amenhotep III were incomplete and the analysis produced differing probability figures despite having concordant allele results. Because the relationships of these two mummies with the KV55 mummy had previously been confirmed in an earlier study, the haplogroup prediction of both mummies could be derived from the full profile of the KV55 data. The identity of The Younger Lady is unknown but she cannot be Nefertiti, as she was not known to be a sister of Akhenaten. However, researchers such as Marc
