  1. CD = chimpanzee deletion; CI = chimpanzee insertion; ERV = endogenous retrovirus; HD = human deletion; HI = human insertion; INDEL = insertion and deletion; LINE = long interspersed nuclear element; ME = mosaic element; SINE = short interspersed nuclear element; SVA = biologically active composite elements consisting of fragments of SINE, VNTRs and Alu elements. Using Rhesus macaque as an out-group, we characterized INDEL variation as CDs, CIs, HDs or HIs.
