"His daughter, Asenath, was the the fairest of all the virgins of the earth; and seemed rather to be a daughter of Israel than an Egyptian"...
She was the daughter of Dina from being raped by Shechem.
Remember also that there is a differnence between Ancient Egypt (Real Mitzrayim) and the Egypt of today that was conquered by Arabs and made into an Arab Muslim country, as well as the mixing between the Arabs and blacks that they made slaves. Arabs still have black slaves to this day and also started the slave trade yet many US blacks are attracted to Islam.
Just like Sadat who looked black. He was part Sudanese. Chaim also said that many Egyptians look similar and have the same facial features as many blacks such as Jesse Jackson and Al Sharpton. The Ancient Egyptians were white (despite what blacks say about how Egypt was black, yet again they say everyone was black, not just North Africans, so they loose their credabilty.).
