Visualizing genomic conservation between human and 41 other species. There are five tracks for each chromosome (from top to bottom): (i) chromosome names; (ii) primates; (iii) placentals; (iv) vertebrates; and (v) ideograms. The human genome has been divided into 2Â MB windows, and for each window the fraction that can be aligned to the corresponding species is plotted as heatmap. The compact non-rectangular layout has been chosen to optimize plotting space utilization for the genome-wide visualization
