Blood properties and coagulation

Hemoglobin polymorphism in the Barbary sheep is reviewed. Electrophoretic, chromatographic, and limited structural analyses have demonstrated that during blood-loss anemia Hb-B of this animal species is replaced by another type, termed Hb-C, whereas a Hb-C like variant, termed Hb-C(na) and present in certain nonanemic Barbary sheep, cannot be replaced when the animal is made severely anemic. Possible genetic mechanisms responsible for these phenomena are discussed.
