Figure 1

Ideograms representative of O. afer (A), C. asiatica (B) and E. edwardii (C) chromosomes. The regions of homology with human chromosomes [see 24, 53, 54] are depicted in red and indicated by the numbers to the left of each chromosomal schematic. In aardvark, homology with the African elephant chromosomes is shown in blue. The location of aphidicolin-induced fragile sites (fs) found in all specimens studied is indicated to the right of each chromosomal schematic in the three afrotherian species. Asterisks mark fragile sites conserved in at least two of the three species studied. Heterochromatic regions are marked by diagonal lines.
