Examples of large-scale disagreements between UMD2 and BCM4. (a) Dot-plot alignment of the region between 15 Mbp and 25 Mbp of chromosome 26 showing a large inversion in BCM4 compared to UMD2; (b) positions of Cmap markers for the same region of chromosome 26, plotted against their positions in UMD2 (blue) and BCM4 (red), showing that Cmap supports the UMD2 assembly. (c) Alignment of 7 Mbp of chromosome 27, showing a large inversion in BCM4 compared to UMD2; (d) positions of Cmap markers for the same region of chromosome 27, showing as in (b) that Cmap is in much closer agreement with the UMD2 assembly.
