CNVRs in GPE bulls. Plot shows the CNVRs identified from the 175 sequenced GPE bull genomes in Circos format (Krzywinski et al., 2009). The outer ideogram runs clockwise from chromosome 1 to chromosome X with labels in Mb of physical distance. The copy number data is represented in the inner tracks. The two innermost tracks show scatter plots of the CNVRs, where the red track shows copy number loss and the green track shows copy number gain. The size of the dot in the scatter plot is proportional to the number of samples containing the CNVR. The other track shows a heat map which indicates the parts of the genome that contain copy number gain and loss. This plot simply collapses the scatter plot values onto a single radial position.
