Genomic distribution of structural variation. The innermost circle shows inversions (grey line) and intra and inter-chromosomal translocations (blue and black lines, respectively). Black bars represent IBD regions identified in the bull. The next circle shows a histogram representing deletions (red) and duplications (green) found by at least two of the CNV platforms; CNVs called by only one platform are in orange. The circle outside the ring of solid coloured chromosomes represents the insertions (green) and deletions (red) found by the mate-pair (BreakDancer) and split-pair (Pindel) analyses.
