Fig. 2.

Micro- and minisatellite diversity in the R. acetosa genome. (A) Rank abundance distributions of short tandem repeats for autosomes and sex chromosomes. Abundance of each unique tandem repeat calculated as percentage of total nucleotides from 1 million reads is on the y-axis. Unique tandem repeats are ranked consecutively within each chromosome library on the x-axis. Curves are displayed on a log–log scale for clarity. (B) Distribution of tandem repeats with respect to their adenine plus cytosine content. Contributions of each chromosome class are stacked in a histogram. Y chromosomes contain notable portions of tandem repeats consisting of pure C and A combinations, which are not true CAA repeats but could hypothetically be derived from them. No other base combination showed such deviation from normality.
