Origins of Inbred Mice documents the proceedings of a symposium on the state of knowledge on inbred mice held in Bethesda, Maryland, in 1978. The book is organized into seven parts. Part I provides introductory remarks on the history of the development of inbred mice. Part II contains papers that examine mutations of inbred strains of mice. Part III contains studies dealing with viruses that affect inbred mice, including those that cause leukemia and mammary tumors. Part IV examines histocompatibility genes and their antigens; cell surface antigens of mouse leukemia; the characteristics of genes of the Tla region of the mouse; and the use of recombinant inbred strains in gene mapping. Part V presents studies on differences among sublines of inbred mouse strains. The papers in Part VI focus on wild mice, covering their classification and biochemical polymorphisms. Finally, Part VIII discusses the viruses, T locus, and histocompatibility antigens of wild mice.
