Comparison of the bovine BAC fingerprint map, composite marker map and Bt3.1 sequence assembly. For each chromosome, top and bottom lines are the composite map, the second line from the top is the assembly, and the third is the BAC map. The upper (blue) region depicts connections between the composite map to the assembly, the middle (green) connects the assembly and BAC map, and the lower (maroon) connects the BAC and composite maps.
