>Calvin has blonde hair >Calvin's father does not

You know who else was blonde? Goku

blonde hair gene is recessive. Both parents can carry it and they still would have dark hair.

So was Johnny Bravo. And some members and ex-members of the Denver Broncos.

Hair can darken over time. I was blindingly blonde as a kid and now it's dark brown.

Neither of my parents have blonde hair, but I was born with blonde hair. As I aged, it grew darker until it was basically the same as my father's hair by the time I was, like, 10.

my brother and my dad both had bright blonde hair that started turning brown when they were about 5, and both have had fully brown hair since like age 9. I still have my blond hair now, but it's not very bright. My hair was so blond when I was 6 years old that it looked white

LIQUID???

My dad had dark brown hair, my mum had black hair, I was blonde as a swede when I was a kid.

Hmmmm...

calvin's mom's hair is brown, so it's probably going to be brown when he's older

Both my parents were born with blond hair which turned brunette around age 9. My sister however, remained blond
