Is brown hair and blue eyes more rare than blond hair and blue eyes?
Wow, that's pretty rare indeed. Do you know why this is the case?
Well, genetics play a big role in determining the color of a person's hair and eyes, and it's thought that the combination of brown eyes and blue eyes is controlled by multiple genes. This means that it's harder for these traits to come together than it is for blond hair and blue eyes, which are both controlled by a single gene.
