Figure 1

Phylogenetic analysis of Alu insertion polymorphisms in guenon genomes. Gel electrophoresisresults of five amplifications used to determine the phylogenetic origin of individual Alu insertions in Cercopithecini species are shown. Upper DNA fragments indicate "filled" sites where Alu elements have inserted, and lower fragments indicate "empty" sites containing no Alu insertion. The DNA template used in each reaction and the locus designation are shown. (A) An Alu insertion specific for terrestrial guenons (C. lhoesti, Chlorocebus aethiops and E. patas); (B) An Alu insertion restricted to the cephus species group (C. ascanius, C. cephus and C. petaurista); (C) An Alu insertion clustering the cephus species group and C. nictitans; (D) An Alu insertion restricted the arboreal Cercopithecus group; (E) An Alu element present in the arboreal Cercopithecus group and M. talapoin.
