title: Genetic mapping and assignment of a long-range repeat cluster to band D of chromosome 1 in Mus musculus and M. spretus.
abstract: A cluster (D1Lub1) of a long-range repeat family was mapped to the proximal part of the Giemsa-negative band D in Chromosome 1 of Mus musculus and M. spretus by in situ hybridization with cloned probes of the long-range repeat family. By making use of restriction fragment length polymorphisms in DNAs from interspecific backcross mice, the cluster could be mapped to a position 5.3 +/- 2.1 cM distal to the Inha locus and the same distance proximal to the Bcl-2 locus. D1Lub1 was inseparable in 114 meiotic events from Acrg, Sag, and Akp-3. Taken together, the data may serve as a reference for coordinating the genetic and cytogenetic maps of Mus Chromosome 1. High-copy-number variants of the cluster, which appear cytogenetically as homogeneously staining regions at the same chromosome location, presumably arose by amplification of the long-range repeat family in situ.
