Using four repetitive sequences, we compared DNAs isolated from Mus caroli, M. cookii, M. hortulanus, M. musculus, M. pahari, M. saxicola, and M. spretus. Except for B1, these probes showed species-specific hybridization patterns. Mouse interspersed fragment (MIF) sequences were present in all species examined, but those defined by the 1.3-kb EcoR1 band were fewer in M. pahari and M. saxicola than in the other species. The Y-chromosomal probe showed male-specific accumulation only in M. hortulanus, M. musculus, and M. spretus, which are known to be closely related. The genetic difference between M. spretus and the other two species (M. hortulanus and M. musculus) was clearly demonstrated by a M. musuclus centromeric sequence that hybridized strongly to M. hortulanus and M. musculus DNA but was underrepresented in the genome of M. spretus. These results may suggest the usefulness of these repetitive sequences in the classification of Mus species that display only subtle morphological differences.
