It is always either black or dark dark brown. Same for eyes, dark brown, or black. Except for the very few that have green and blue eyes which is very rare. Why are these color genes extremely rare in these countries? Why is it so common in Europe to see a group of people with vast different hair colors and eye colors?

To have a sudden trait pop up out of nowhere is called a mutation. Because your mother had a nose and your father had a nose, and these noses were in their genetic code, YOU have a nose. No surprise there, right?

Certain regions of the world are going to have certain traits (dark skin, light hair, blue eyes, taller structure, etc) because that is simply what is passed down to them. If you had the lightest blond hair and had children in Japan with a Japanese woman, there is a CHANCE that your children would have light hair too. But your grandchildren will have darker hair... and great grands darker still. After a few generations your blond hair genes will have dissipated into the black hair genes that surround you.

(This is why certain countries like the U.S. are called "melting pots": so many genes mixing together that you can have all kinds of results.)

I would think that the reason that chinesse or japanese people have natural hair colors other than black is because they usually tend to marry in their race. Getting the diffrent hair colors is usually because of mixing races. It might not show up in their kids but aftrer several generation it usally tends to show up, maybe in the form of diffrent colored eyes. African American people don't have hair color other nautral black or brown. Every once ina while there will be an african american with naturally red hair and that is because of genes in their body that had remainded dormant in the parents but showned up in that person
