A genetic mutation could explain why some people are born blonde.
Scientists at Stanford University have identified a slight change in the genetic code that determines if someone will be a blonde or brunette.
This mutation is completely unrelated to any other inherited trait.
That means hair color has no effect on hair growth, eye color, skin color, personality or intelligence.
