Figure 3.

The number of short tandem motifs. This chart shows a distribution of the number of distinct motifs with the same length. Unlike the abundancy of tandem lengths (Figure 2), the tandems with lengths up to around 20 show similar profiles in all three species. Most of the differences are hidden in lengths 20–40 nt. Particularly in A. ursinum, there is a very large increase in the number of distinct motifs around lengths of 23–30 nt. In the case of A. sativum, several peaks are detected, e.g., in lengths of 23, 27, and 34 nt.
