Abstract

The expression of nucleolus organizer region (NOR) activity in diploid cells was investigated in a model mammalian hybrid system, the hinny (female ass x male horse), by sequential Ag-NOR and chromomycin A3/distamycin A/DAPI (CDD) staining in lectin-stimulated peripheral blood lymphocytes. In the majority of cases we found non-expression of the horse-derived NOR chromosomes in the hinny. However, in one case there was strong NOR expression on horse-derived chromosome no. 1.
