This has been the subject of speculation for a long time, but now there is a peer-reviewed paper confirming the last rulers of the 18th Dynasty belonged to paternal haplogroup R1b.
Gad et al. seem to suggest the reason for the delay publicizing results has been due to controversy surrounding contamination. Seeing how remains are moved by a bunch of sweaty guys raining over a mummy being moved coffin to gurney, it's easy to understand the reservations.
I'm going to guess that subsequent papers are queued up with more 17th and 18th Dynasty profiles. Just guessing.
As we've seen with the two papers on the German Beaker farmstead genealogies, there is potential to really expand the knowledge on relationships spanning hundreds of years in Egypt. New questions will emerge, such as, what was driving the chaos of the whole 2nd Intermediate Period, what role did mercenaries play in forming new social classes, who were the barbarians invading?
I will assume for now (barring cuckoldry somewhere along the way) that Ahmose I was also R1b of the Atlantic type. But then the question, how many generations into the 17th dynasty?
For some reason I had it imprinted on my mind that Tut had a Sub-Saharan mtdna profile, like L-something. Not the case here. He's a Near Eastern K-boy. That's unexpected, at least for me.
