The cosmid CSSM25 assigns syntenic group U2 to bovine chromosome 9 and is localized to ovine chromosome 8.
The cosmid-derived microsatellite CSSM 25 has previously been shown to map to bovine syntenic group U2 by linkage and hybrid somatic cell analysis. We have mapped the cosmid by fluorescent in situ hybridization to bovine Chromosome (Chr) 9q17-21 and ovine Chr 8q17-21 and hence assign U2 to Chr 9 in cattle. Bovine Chr 9 and ovine Chr 8 show strong banding pattern homology, and the localization of CSSM 25 to the same region confirms the strong conservation of gene locations on these chromosomes.
