AC,

Most black American men with euro yDNA are R1b -- exactly as Tut is.

This is exactly why we never hear about mtDNA on Egyptian mummies; by mentioning only that the yDNA is largely European, and ignoring the mtDNA, it allows people to draw incorrect conclusions.

A glaring example is the Wikipedia list of mtDNA tested mummies: http://en.wikipedia.org/wiki/List_of_DNA_tested_mummies

Note the question marks next to the Egyptians.
