 The two pairs of characters may be: straight dominant 

 to its absence (curly), and straight dominant to wavy.

 wavy and curly in the proportions: straight !), wavy .", and 

 curly 4. The actual number of children with the different 

 kinds of hair is straight .">.'!, wavy 6 and curly 21. 



The results of crossing straight and wavy hair may 

 profitably be considered at this point.
