Abstract

Three cases of morphologic variants of human D- or G-group chromosomes have been studied by N- and Ag-AS banding techniques. The results confirm our previous findings about the localization of nucleolus organizers on the secondary constrictions of acrocentric chromosomes. Preliminary results on the distribution and number of N bands in D- and G-group chromosomes with morphologic and fluorescence variants are reported.
