MDR plots of a BARE1 LTR retrotransposon and a Caspar DNA transposon. The linear scale (top) illustrates the strong variation in relative abundance between the two elements but also of different regions within the two elements. The LTRs of BARE1 are roughly 3-fold over-represented whereas a region containing tandem repeats in the Caspar element are at least 20 times more abundant than the rest of the element. The grey box indicates a region of low-complexity DNA. The logarithmic representation allows an easy identification of variable regions (e.g. in the BARE1 LTR and between the two CDS in Caspar).
