Eye color genetics question?
 

I was born to a pair of blue eyed parents and four blue eyed grandparents. So how is it possible that I ended up with hazel eyes?!?

There is no question about my parentage or my parents either. No mailman scenario.

hazel/brown eyes are dominant over blue eyes and if your grandparents were recesive for hazel eyes ie Bb bb and Bb bb and passed on this to your parents who both ended up being recessive Bb bb you could end up being BB bb and have hazel eyes
