Correction to: Limited MHC class II gene polymorphism in the West African chimpanzee is distributed maximally by haplotype diversity.

The authors regret that an error was present in the Fig. 5 of the above article; some digits in the DRB allele-designations in Fig. 5 have been lost, and are incorrectly presented by only two digits. The correct allele-designations should have been four (or six) digits. The correct Figure is now presented correctly.
