| first report of major histocompatibility complex class ii loci from the amazon pink river dolphin (genus inia). | we report the first major histocompatibility complex (mhc) dqb1 sequences for the two species of pink river dolphins (inia geoffrensis and inia boliviensis) inhabiting the amazon and orinoco river basins. these sequences were found to be polymorphic within the inia genus and showed shared homology with cetacean dqb-1 sequences, especially, those of the monodontidae and phocoenidae. on the other hand, these sequences were shown to be divergent from those described for other riverine dolphin speci ... | 2006 | 17117356 |
