I believe colorblindness is an X - linked recessive trait.  As a result, 
males are more likely to be color blind if their mom is a carrier and passes 
that gene along.  The father does not contribute to the males because he 
passes the Y - gene to the males.  Females are less likely to be colorblind 
because it is less probable they will a recessive X - gene from each of 
their parents.
