If both parents have blonde hair, why can their children have brown, red, or very dark hair?

Answer:

cause of genetics, it is super rare to find someone who has blonde hair but both of their parents have red unless the kid got a condition turning her hair into a different color, but in fact, A brown allele would have dominated, resulting in brown hair. If both parents carry only blonde alleles, they can only pass on blonde alleles, therefore, their child must be blonde, But yeah that is definitely possible. Not that common, but it does happen. ... If neither parent passes it to their child, then that child may very well end up with darker hair and skin than either parent.
