Surely their superior genes would triumph and if they didn't it was because they were weak and weakness should be bred out. It never made any sense. And now we know that blond hair and blue eyes are themselves a genetic mutation from the darker norm.
Mutations survive in populations because they assist in the survival of the species in different environmental situations. Skin and hair with less melanin allows better absorption of sunlight in northern climes, and therefore, higher production of Vitamin D to aid in absorption of calcium from the gut to produce stronger bones, etc. Light-colored irises provide more light absorption in the eyes, but dark-colored irises protect the eyes from the strong sunlight of the more tropical environments. They are both genetic variations, but for different reasons.
People from Africa who are currently living in places like Sweden, Norway, and Finland would probably tend to have Vitamin D deficiencies for the lack of enough sunlight exposure. Vitamin D deficiency is also a problem in temperate climate zones because so many people live and work indoors so much of the time. I take Vitamin D aupplements every day.

Biologists have known about "hybrid vigor" (mixing of genetic materials) in living organisms. Human beings of different races have been doing more than just saying "Howdy" to each other for millions of years, and so did our hominid ancesters, and thereby by doing so, we have evolved genetically to what we are today.
