  1. aNumber of loci that integrated after the divergence from the macaque (31.6mya) but before the divergence from the chimpanzee (6.6mya). All loci represented by the pre-integration site in the macaque (or baboon).
  2. bNumber of loci that integrated after the divergence from the chimpanzee (6.6mya). Loci represented by the pre-integration site in the chimpanzee.
  3. cThe number shown in parenthesis is that expected if a single integration rate was applied to both time periods.
