Gene based comparative map of SSC 7q1.2 and BTA 23q11 radiation hybrid maps and HSA 6p21.32/HSA 6p12.1-q112 physical map. A- SSC 7q1.2 radiation hybrid map was build using IMNpRH2₁₂₀₀₀ developed by Yerle et al [7]. B- BTA 23q11 radiation hybrid map was build using RH5000 panels developed by Williams et al [22]. The human physical map corresponds to NCBI build 35 produced by the International Human Genome Sequencing Consortium. Markers in bold on the RH map belong to the framework map, whereas markers in italic are mapped at their most likely location considering as fixed the distance between framework markers. The centromere is represented by a circle. Arrows indicate blocks of gene whose order is conserved among the three species. Hatched box on the SSC7 RH map represents a fragment where no gene mapping information is available.
