Synteny map for Mus spretus versus Mus musculus. A. Map of the 690.4-kb Mus musculus V1Ra/V1Rb gene cluster on chromosome 6 (89617451–90307871 in July, 2007 assembly, UCSC Genome Browser) showing flanking non-V1R genes (Txnrd3, Uroc1) and the 16 intact V1R genes in the cluster. LINE repeats (black stripes) are shown below gene annotations. The locus assembly in Mus spretus is shown above the musculus map, with the ordered contigs indicated by rectangles (contig numbers and orientations above/below rectangles). The total spretus assembly is ~716.5 kb. Dotted boxed regions indicate the unresolved spretus assembly corresponding to the V1ra3-V1ra4 region in musculus and the presumed deleted segment in spretus corresponding to the V1ra8-V1rb3 region in musculus. The contiguity of the spretus-musculus assemblies are illustrated by the diagonal in the dot matrix in panel B.
