The map has been developed using a recently constructed 12 000 rad bovine-hamster whole-genome radiation hybrid panel. Moreover we present a comprehensive map of BTA13 comprising 72 loci of which 45 are microsatellites 20 are genes and seven are ESTs. The map has an estimated length of cR12 00Q. The proposed order is in general agreement with published maps of BTA13. Our results only partially support previously published information of five blocks of conserved gene order between cattle and man. We found no evidence for the existence of an HSA20 homologous segment of coding DNA on BTA13 located centromeric of a confirmed HSA10 homologous region. The present map increases the marker density and the marker resolution on BTA13 and enables further insight into the evolutionary development of the chromosome as compared to man. bovine chromosome 13 .
