Parallel RH mapping of BTA1 with HSA3 and HSA21. Academic Article uri icon


  • The development of radiation hybrid (RH) panels has elevated comparative gene mapping to a new level of resolution. In this study, we have constructed parallel RH maps defining rearrangements of gene order within conserved segments of bovine Chromosome (Chr) 1 (BTA1) and human Chrs 3 and 21 (HSA3, HSA21). Six new markers, including one gene, have been added to the bovine map, and 11 human genes were ordered with the human G3 panel. BTA1 is clearly a composite of genetic material conserved on these two human chromosomes with HSA21 homologs at each end of BTA1 flanking a large segment homologous to HSA3. Each of the three conserved segments of BTA1 contains rearrangements of gene order relative to their human counterparts.
