Someone else in one of your family's must have them.. I have green eyes, my mom or dad don't have them but my great grandpa had green eyes, so that's were I got them from.
Exactly^^ traits can skip generations based on if they are dominant or not. Me and both my parents have green/blue eyes and my brother has brown eyes. I have a grandparents on either side of the family withbbrown so that's where his come from.
