The chromosomes of the Great Indian Rhinoceros (Rhinoceros unicornis L.).

Female in Washington zoo. Diploid number determined to be 82. 10-12 pairs of chromosomes appear to have subterminal and all the rest terminal centromeres. The autoradiographs showed one of the largest chromosomes, and the most metacentric of the complement, to be late labelling. This pair is therefore taken to be X-chromosomes. Chromosomes in Ceratotherium simum appear to be similar, although indian rhino may possess several more subterminal and several less terminal elements than the white rhino.
