Association of nucleolus organizer chromosomes in domestic sheep (Ovis aries) shown by silver staining.

L M Henderson, A N Bruère.   

Abstract

The nucleolus organizer regions of domestic sheep (Ovis aries), as shown by silver staining, are located terminally on chromosomes 1, 2, 3, 4, and 25. Significant differences between individuals in the number of Ag-NORs per cell were found. The frequency of involvement of individual chromosome pairs in nucleolar organization was found to be a characteristic of individual animals. Association frequencies of individual chromosomes were accounted for by their frequency of participation in nucleolar organization. No evidence for nonrandom association of chromosome pairs was found.
