Codominance differs from incomplete dominance because in incomplete 
dominance, the colors blend, much like when you blend paint and achieve a 
new color.  In codominance, both colors are present, but blend together 
when looked at from a certain distance.  When looked at closely, however, 
the both red and white can be seen.
