Abstract Background Indian muntjac Muntiacus muntjak vaginalis has an extreme mammalian karyotype with only six and seven chromosomes in the female and male respectively. Chinese muntjac Muntiacus reevesi has a more typical mammalian karyotype with 46 chromosomes in both sexes. Despite this disparity the two muntjac species are morphologically similar and can even interbreed to produce viable albeit sterile offspring. Previous studies have suggested that a series of telocentric chromosome fusion events involving telomeric and or satellite repeats led to the extant Indian muntjac karyotype. Results We .
