Association between pairs of SDs and primate reversals. (A) Simulations showing the enrichment of pairs of SDs within the primate breakpoints; (shaded area) the distribution of values observed in 1000 matched random data sets. (B) Average sequence identity of pairs of SDs associated with the primate reversals that are human specific, human–chimp (HC) specific, or human–chimp–rhesus (HCR) specific. nb, number.
