“…Besides their domestication or maintenance as active, inactive, or domesticated copies, the ‘sympatry’ of TEs in the nuclear environment enables new mosaic elements that are active in transposition to emerge. To date, such composite elements have been reported in several taxa, and result from recombination and transposition events between Class‐I retrotransposons (Li et al ., 2009), a retrotransposon and a gene, non‐TE repeats such as satellite DNA or variable number of tandem repeats (VNTR; Fudal et al ., 2005; Wang et al ., 2005; Souza et al ., 2007), or between Class‐I and Class‐II elements (Nakajima et al ., 1999; Palomeque et al ., 2006). Depending on how they originated, these composite elements can move by either retrotransposition or transposition, the hallmark of their mobility being in general that they are flanked by a target site duplication (TSD).…”
