I understand about recessive and dominant genes, and how to use the 
Punnett squares.  Simply, crossing bb and bb can't produce a BB or Bb, but 
I know that it has been known to happen.  How and why?  I am struggling 
fiercly to explain to my brother-in-law how he could have a brown-eyed 
child when he and my sister have blue eyes.  Please help.  I think he's 
worried the baby isn't his!!
