Mbp and cM were determined using the Mouse Genome Informatics website 12 and genotyped by S.S. Malhotra and E.L. Travis; data not shown. #: major histocompatibility complex (MHC) H2 haplotypes according to MHC H2 Haplotype Appendix 2 13; ¶: background strain for 2R, 4R and 5R mice; +: donor strain for 2R, 4R and 5R mice; §: background strain for C3H-H2b mice.
