DNA copy numbers. a Plots of mapped DNA read density along the genome. Deduced copy number is indicated by color (see key). b Heatmaps display how many cell lines have increased (green) or decreased (red) copy number. Black lines in the first two rows show significance. Blue lines indicate breakpoints. Black in the bottom row shows the number of breakpoints shared by the 19 cell lines. c A zoomed-in map of the sub-telomeric region (1 Mb) of chromosome 3 L. Asterisks: genes within the highly duplicated regions. Genes with little or no functional information (‘CG’ names) were omitted for brevity
