I did not read all of what everyone had to say. Sorry. I just wanted to speak my mind.....<3 to everyone, do not be offended....
Issue number one: Nefertiti only had daughters, yet there is the relief of Akh and Nef mourning over a woman who died in childbirth-the result? A baby with the ostrich plume fan over 'it'. Conclusion-A royal birth has occurred, and it was not Nefertiti's.
Issue Number Two: The body in Kv 55....It's sex has been argued over since it's discovery. Yet, Tut and this body share the same bloodtype. Meaning they are brothers or father and son. Conclusion: Akh's illness would have made it hard to tell by the fusion of bones alone, according to age. The skull shape matches his representations, and we have no reason not to believe that he did not appear as such. Besides that, the body has wide hips LIKE A WOMAN. No other royal male reaches this protocol. (Forgive my spelling.)
Issue Number Three: Tut shared the same illness Akh had. Evident in kilts and loinclothes found in his tomb by the Swedes. (No direspect intended.) He has HIPS too. Conclusion: Marfan's can only be passed through genes.
Ultimate conclusion: Akhenaten is Tut's father. (I have more proof; however, my brain farted and told me to go screw myself.

) If anyone finds any holes, please let me know. I will gladly fill them up for you!!!

(no I am not intending to sound...mean.)
