Figure 4

Density and distribution of repetitive DNA on each chromosome of T. castaneum. The total length (kb) of repetitive DNA in each 500 kb interval along the chromosome is plotted. The 300 kb placeholders were not included in the chromosomes. Sequencing gaps are included in the calculation if they are ≥50 bp. The length cutoff for parsing the RepeatMasker results was 50 bp. The HighA class includes the 360 bp satellite. Gene number, gap length and distribution of other repetitive classes within the 500 kb intervals are shown below the main graph for each chromosome. The combined average of HighA repeats and TE per 500 kb along the chromosome is depicted as a black line.
