Hereditary Differences in Serum Proteins of Normal Mice.

In a study of the serum proteins of 7 mouse strains, it was established that there were inherent differences in the electro-phoretic patterns and in the amount of total serum protein. A distinct β-globulin component was found in only one, E, of the strains. The hybrid progeny of this strain also had this globulin component in their serum. This indicates that the protein is probably determined by a dominant gene (or genes).
