Identification and annotation of GSSVs. (A) The cladogram indicates the phylogenetic relationship among the analyzed primate species. We used the high-quality genomes of four great ape species, one lesser ape species, and one Cercopithecidae species. The numbers of SVs and their genomic lengths based on assembly comparisons are indicated. DELs are the numbers above the lines and INSs are those beneath the lines. The number in the box indicates the identified 15,885 GSSVs, including 7,728 DELs and 8,157 INSs. (B) Chromosomal distribution of the identified GSSVs. The number of SVs is tightly correlated with the length of the chromosome, as indicated by the Pearson correlation (R² = 0.95, P = 6.7e⁻¹³). (C) The size distribution of GSSVs. The two peaks at 300 bp and 6 kb indicate the Alu and L1 elements, respectively. (D) Annotation of GSSVs located in the repeat regions of the genome, where SINEs (such as Alu) and LINEs (such as L1) compose of the great majority of the identified GSSVs.
