title: A linkage map of mouse chromosome 12: localization of Igh and effects of sex and interference on recombination.
abstract: Inheritance of restriction fragment length polymorphisms associated with four anonymous DNA markers (D12Nyu1, 2, 3 and 4), the Fos proto-oncogene, the Mtv-9 viral integration site, and the alpha 1-antitrypsin (Aat-1) and immunoglobulin heavy chain (Igh) gene families in the mouse has been followed in a backcross experiment. A Bayesian multilocus map-building strategy yielded the map: centromere-D12Nyu2-10 cM-D12Nyu1-2 cM-D12Nyu3-15 cM-Fos-1 cM-D12Nyu4-2 cM-Mtv-9-8 cM-Aat-1-17 cM-Igh-C. A map constructed from male meiotic data was substantially shorter than one constructed from female meiotic data. Significant interference was observed for the linkage group. Two groups of markers studied in recombinant inbred strains of mice could be interpolated into the map: Es-25, D12Nyu10, D12Nyu7 and Apob form a cluster proximal to D12Nyu2, and Ly-18, Ah, and D12Nyu5 form a cluster between D12Nyu2 and D12Nyu1. These data establish an unambiguously ordered linkage group including Igh and Aat-1 that spans most of chromosome 12.
