Muslim Egyptians are 25% Sub Saharan African sometimes even more, Copts weren't involved in the Slave Trade?
It is closer to 17-19%. But most studies I have seen usually sample Delta Egyptians. I hear it is 20-27% for Central and South Egyptians (non-Nubian ones).
I heard Iran also had a large Black Slave population.
Apparently it did not affect Iranians much. Only some near Basra/Kuwait and around the Gulf coast.
