Abstract
Immune responsiveness of inbred mice to low doses of ovalbumin or ovomucoid is under control of single dominant genes closely linked to alleles of the H-2 locus. High responsiveness to ovomucoid is linked with the H-2(a) and H-2(k) alleles, and to ovalbumin with the H-2(b), H-2(d), and H-2(q) alleles.
