Abstract
Haemoglobin variants were studied in wild and laboratory house mice (Mus musculus), including standard and new inbred strains, using starch-gel electrophoretic technique. Single (Hbbs) or diffuse (Hbbd) types of haemoglobin were found in all of them. The embryonic haemoglobin pattern was different from although similar to that of the adult in all the strains. The haemoglobins revealed monomorphism in the inbred strains, while polymorphism was observed in non-inbred laboratory and wild mice.
