[i] Predictions are separated by species and category. Bin indicates number of virtually mapped unique homologous UniGenes predicted within a conserved segment. Stream indicates number of UniGenes predicted to fall directly upstream or downstream of a unique homologous UniGene anchor currently defining an evolutionary breakpoint prediction. Some predictions are made using conserved segment information from one species and others have been made using both comparative species. The predicted UniGenes have been integrated into the clickable maps found at http://rgd.mcw.edu/VCMAPS and can be queried using the cR distance flanking a region of interest, or by clicking on the rat map backbone.
