Mapping length ratio distribution for the alignment of genome sequences upon genome maps. The mapping length ratio, defined as map length divided by total length, were estimated for reference genome 2014draft [11] (green) and 2015draft [12] (orange). Only mappings with the highest confidence score of each genomic sequence were collected for the analysis. Note that small mapping length ratios may represent large scale nicking site heterozygosity or mappings at map ends
