SSR lengths across subgroups. a The top 100 longest repeat instances from each organism are recorded separately and the data for organisms falling in the same subgroup are then grouped. Box plots showing the range of the longest 100 repeat lengths in the organisms of a particular subgroup are plotted. Color indicates the main group to which the subgroup belongs. b The percentage of occurrence of a repeat class in the top 100 longest SSRs across all organisms is calculated to select SSRs that occurred at least 1% of the times. The average percentage of these ‘highest occurring’ SSRs across organisms in each subgroup is plotted (Y-axis), categorizing the rest of the SSRs into “Other”. Individual SSRs are color-coded as indicated. The 15 subgroups are labeled along the X-axis
