The rabbit (Oryctolagus cuniculus) α-like globin gene cluster (HBAC) contains several block duplications of ζ-, α-, and θ-globin genes. Using in situ hybridizations to metaphase chromosome spreads, the gene cluster has been mapped to region q12 of chromosome 6. Given that human HBAC maps to the short arm of chromosome 16, the mapping of rabbit HBAC to 6q12 confirms the assignment of homology between OCU6q and HSA16p based on similarities of chromosomal banding patterns. In both species, HBAC is in a very G+C-rich region within the most distal band of the chromosome.
