  2. The TEs contents of three regions of the genomes were compared: SDs regions; 2.5 Kb flanking regions (FR) of the SDs and the genome average. Enrichment was defined as the repeat content of duplicated sequences divided by the repeat content of unique sequences. The significance was performed by simulating the repeats in a random sample (n = 1,00) of DBM SDs (P-value < 0.05 were in bold)
