| Abstract: | Summary The frequency of involvement in satellite association and the frequency of selective staining of the secondary constrictions with silver solutions have been studied in five phenotypically normal individuals, all carriers of morphological variants of the nucleolus organizing region (NOR). The results show the preferential involvement of some morphological markers in satellite association, and also their preferential staining with Ag-I. It has also been shown that acrocentric chromosomes involved in satellite association are always stained by silver. |
