The genus containing various species of small deer living in India, Nepal, and southeast Asia. The Indian muntjac, M. muntjac vaginalis, is remarkable in having the smallest chromosome number known for any mammal (6 per diploid female). The Chinese muntjac (M. reevesi) has a larger diploid value (46). During evolution, the chromosome number of the Indian species appears to have decreased by end-to-end fusions between different chromosomes. The amount of DNA in diploid nuclei from the two species is about the same. See Chronology, 1997, Yang et al.; chromosome painting.
