title: Location of the second gene required for expression of the leukemia-associated mouse antigens G IX .
abstract: Some mouse strains express G(IX) antigen on their thymocytes; others do not. Expression depends on two genes, Gv-1 and Gv-2, in linkage groups IX and I, respectively. Cells producing leukemia virus, however, express G(IX) antigen regardless of their inherited Gv-1 and Gv-2 genotype.
