Consensus genome map overview. An overview is shown of the 3338 consensus genome maps (teal), from cell line 778, aligned to the human reference genome, GRCh38. Overlapping alignments to GRCh38 (i.e., alignment density) is reflected in the color gradient of the genome maps. The reference genome is represented by its cytogenetic G banding (UCSC Table cytoBandIdeo, last updated June 11, 2014), in which dark to light gray in this figure correspond to Giemsa stain intensity, centromeric (acen) bands are represented in red, variable heterochromatic region (gvar) in pink, and stalks (tightly constricted regions) in blue. The breadth of coverage is theoretically limited to 90% of the reference genome due to uninformative regions, including acen, gvar, and stalks.
