The abundancy of short tandem motifs. The chart shows a distribution of the detected reads with tandem motifs of a specific length. Height of the bars represents the number of reads and the position corresponds to the increasing lengths of the motifs. The most frequent lengths are 4 nt in A cepa, 27 nt in A. sativum and 30 nt in A. ursinum. The majority of repeats is not distributed equally in the three species. A. cepa has most of the tandems around 9–18 nt, A. ursinum has a majority around 23–30 nt, and A. sativum shows peaks of 5, 9–15, 19, 23, 27, and 34-nt long motifs.
