The chromosomal karyotypes of two species of small deer, the Reeves muntjac and the Indian muntjac, are strikingly different despite the fact that the two genomes contain about the same amount of DNA. However, within a species, there are properties of chromosomes that are the same, i.e. species-specific. Select the answer that contains all of these species-specific properties of chromosomes at metaphase
