Figure 3.
The repetitive element landscapes of the F and the base of the D elements in D. melanogaster (red), D. erecta (orange), D. mojavensis (blue), and D. grimshawi (purple). (A) WindowMasker analysis (low complexity repeats and transposons); (B) tantan analysis (simple and low complexity repeats); (C) Tandem Repeats Finder; (D) RepeatMasker analysis (transposon density). Within each species, the F element generally shows a higher repeat density (particularly transposable elements) than the euchromatic reference regions from the D elements. Except for tandem repeats, the base (light orange), extended (olive), and telomeric (green) regions from the D. erecta D element generally show similar repeat density.
