Nucleolus organizer region location and 'ring' chromosomes in the bharal.
Silver-staining has been used to identify the nucleolus organizer regions (NORs) in the bharal. These show homology with sheep, goat, cattle and aoudad. The association of the NORs on both telomeres of chromosome 3 results in a 'ring' chromosome.
