Who was King Tutankhamun's mother ?

Two mummified fetuses found in the tomb of King Tutankhamun will undergo DNA testing to determine their relation to the famous pharaoh, Egyptian officials announced today. The fetuses may also solve a longtime puzzle: the identity of King Tut's mother. The young Tut, who reigned from 1336 to 1337 B.C., is controversially thought to be the son of Pharaoh Akhenaten and his wife Kiya. But some archaeologists believe he could be the son of Akhenaten's other wife, the powerful Queen Nefertiti. "The fetuses will help us determine whether [King Tut's wife and daughter of Nefertiti] Ankhesenamun was a half sister or a full sister," said Zahi Hawass, secretary general of Egypt's Supreme Council of Antiquities. "If the fetus DNA matches King Tut's DNA and Ankhesenamun['s DNA], then they shared the same mother." - mystery
