SV within the genome of 53 inbred mouse strains. (A) Letter-value boxplots show the size distribution of deletion, duplication and inversion SVs, which have a median length of 337, 680, and 362 bp, respectively. The total number of each type of SV is shown at the bottom. (B) The SVs are categorized into four subgroups according to their size: 50–500 bp, 500 bp-5 kb, 5-10 kb, and > 10 kb. Over 90% of the deletions are < 5 kb, 97% of the inversions are < 5 kb, but 19% of the duplications are > 10 kb. (C) The number of SVs are categorized according to their type and chromosomal location, and by the number of inbred strains with a strain-shared SV. Each box color indicates the number of each type of SV according to the scale shown at the top. A white area indicates that shared SVs were not found for that number of strains. Deletions are the most common type of SV, and the majority are uniquely present in one strain
