Segregation patterns of endogenous mouse mammary tumor viruses in five recombinant inbred strain sets

We identified mouse mammary tumor proviral loci in the AKR/J, C3H/HeJ, C57BL/6J, C57L/J, DBA/2J, and SWR/J inbred mouse strains and determined their segregation patterns in the AKXD, AKXL, BXD, BXH, and SWXL recombinant inbred strain sets. Two new Mtv loci, Mtv-29 and Mtv-30, were identified. Mtv-30 was genetically mapped to chromosome 12. Additionally, two previously identified Mtv loci, Mtv-14 and Mtv-23, were genetically mapped to chromosome 4 and chromosome 6, respectively.
