Nubians are not 100% negroid. Egypt colonized Nubia over the course of 1,000 years, which explains why.
"The low number of private alleles found for the Beja (0.031 ± 0.012)
and the Nubian (0.129 ± 0.040) groups could be the result of high
migration rate and greater gene flow from Eurasian populations." Babiker

"Nubians have sustained considerable gene flow from Asia and Europe." Cavalli-Sforza 2008
What nonsense are we going to be subjected to next, clown?
