From: The generation of chromosomal deletions to provide extensive coverage and subdivision of the Drosophila melanogaster genome

Figure 2

Frequency distribution of the number of genes between molecularly defined deletion breakpoints. The number of genes in a chromosomal interval between adjacent deletion breakpoints is shown on the x-axis and the number of intervals in the Drosophila genome with those sizes is shown on the y-axis. Because BSC, Exelixis and DrosDel deletions overlap extensively, the intervals were usually defined by breakpoints of different deletions. The median interval size is only nine genes. For simplicity, the Stellate gene cluster in chromosomal region 12E, the histone gene cluster in 39D and the 5S rRNA gene cluster in 56E were counted as single genes.
