Fig 1. Schema and characteristics of repeat regions across genome.

(A) Schema of repeat regions. Regions with only one type of motif are called pure repeat region while those with both GGAA and TTCC are called mixed repeat regions. Each repeat region (purple box) is separated by at least 20-bp consecutive non-motifs. (B) Histogram of maximum number of consecutive motifs. (C) Histogram of total number of motifs. (D) Histogram of motif density of repeat regions. $Density=\left(\frac{totalnumberofmotifs\times 4}{lengthofregions}\right)\times 100\%$. Bin width is 5%. (E) Histogram of length of repeat regions. Each bin is 100bp width (e.g., first bin is 0-100bp length). Bins with zero repeat regions are not shown. (F) The characteristics of repeat regions for pure and mixed repeat regions across the genome. Red line indicates the mean for each characteristic.
