Abstract
Combined autoradiography, giemsa and fluorescence banding studies have been completed on the chromosomes of the rat kangaroo (Potorous tridactylis) and the Indian deer (Muntiacus muntjac). Autoradiographic analyses of these established heteroploid lines revealed an absence of a late replicating sex chromosome. For the muntjac complements there appeared to be a correlation between grain concentration and regions of bright fluorescence or dark giemsa stain. Specific banding studies revealed that numeric chromosome changes had taken place in the muntjac lines, with the chromosomes showing no obvious structural alterations from the diploid state. Karyotype changes in the rat kangaroo line were complex and involved structural rearrangements.Keywords
