Question

Why do blonde hair and blue eyes tend to go together?​

Answer 1

Explanation:

The first is that blue eyes and blonde hair both come from having less of a pigment called eumelanin. This is just something the two traits have in common -- they are not because of the same gene. When genes like these are close together, the traits tend to end up coming in pairs (blonde hair/blue eyes, etc.).

Answer 2

Heya!!

There are ways that someone with a recessive trait, such as blue eyes, can carry a dominant gene and even have a child with brown eyes.

Eye and hair color depends on the distribution of melanin.

It’s rare that you would have darker hair and eyes than your parents but not impossible.

Thanks!
