Subject: How did my nephew get blonde hair and blue eyes?

My nephew is a blue eyed blonde.  His father and paternal grand-
parents are all dark eyed and dark haired.  My sister is a hazel-
eyed blonde. Our mother is a blue eyed blonde, while our father
has dark hair/hazel eyes.  Each of us kids inherited dad's hazel
eyes.  Isn't dark/dark dominant?  My sister jokes that her son doesn't
look like his dad, i.e., dark/dark, but I know she'd like a scientific
answer.  Thanks!
