Abstract

The genomic activity and polymorphisms of nucleolus organizer regions(NORs) were studied in an individual with routinely used AgNO3 and Q-banding techniques. The results demonstrate that (a) the mean number of NORs per metaphase spread was 7.4, (b) chromosomes 14, 13, 15, and 21 showed variations of Ag-NOR in decreasing order, (c) chromosome 22 did not show a polymorphism in any cell examined, and (d) both chromosomes 14 showed silver staining in most cells, Unlike many earlier reports indicating that NOR variants were constitutional in each individual, our present case represented a mosaic pattern of polymorphism involving most of the D- and G-group chromosomes.
