It's clear that Cleopatra was mostly Greek with a a potential admixture of native Egyptian ancestry. Native Egyptians were not black Africans though some may have been partly black; ethnically they were closer to Arabs and Berbers (Berber languages in particular are close to ancient Egyptian etymologically). Plus, considering that most of the Ptolemies married their sisters and nieces in what is arguably the longest-running history of direct family incest in recorded history, her family tree resembles a line, and there were limited opportunities for native Egyptians to diversify the DNA.

However, I'm not sure why that means calling Egyptians "wogs" or placing the blame for the plight of Africa solely on the inability of said "wogs" to govern their "craptacular continent" is acceptable.
