a second site for checdna hybridization was found on chromosome 16p11-q23 , demonstrating that the che2 locus of the cholinesterase gene , which directs the production of the common c5 variant of serum che , also codes for a structural subunit of the enzyme and is localized on the same chromosome with the haptoglobin ( hp ) gene , both genes being found on the long arm of chromosome 16 .
