Description: English: a. Metaphase spread of the Indian muntjac (Muntiacus muntjak vaginalis, 2n = 6, 7), the species with the lowest chromosome number. b. Metaphase spread of the Viscacha rat (Tympanoctomys barrerae, 2n = 102), the species with the highest chromosome number. c. Metaphase spread of the Siberian Roe deer (Capreolus pygargus, 2n = 70 + 1-14 B's). The species with additional, or B- chromosomes. d.
