The dividing line between intermediate inheritance and co-dominant inheritance is fuzzy. Codominance is more likely to be used when biochemistry is concerned, as in blood types. Codominance means that both alleles at a locus are expressed. Codomininance in X-linked genes is a special case that will be treated under sex-linked inheritance.
