Abstract
A silver staining method was used to analyze the distribution of nucleolar organizer regions (Ag-NORs) on chromosomes of 45 wild mice (Mus musculus). The four subspecies represented were M. m. musculus, M. m. molossinus, M. m. castaneus, and M. m. bactrianus. Ag-NORs were observed near the centromeric regions of 11 chromosomes (4, 8, 9, 10, 11, 12, 15, 16, 17, 18, and 19), indicating a preponderance of Ag-NORs on smaller chromosomes. The first five loci have not been observed previously. It is suggested that a correlation may exist between the specific features of mouse Ag-NORs and the events involved in intra- and interchromosomal homogenization of rDNA.Entities:
