Vombatus ursinus (Naked-nosed wombat)
Chromosome preparations from lymphocytes of two female wombats at San Diego Zoo confirm earlier reports. Although testicular preparations from two males are reported by Sharman, the Y is neither described nor depicted. Also, no positive identification of the X chromosome has been made. The second karyotype here shown is prepared with C-bands and only because of the different appearance with large C-blocks, is the last pair singled out as the possible X. It is the same element which Hayman and Martin describe as having satellites.
