摘要：

This study provides new data on zebrafish chromosomes, obtained from the chromomycin A(3)-banding pattern and mapping of 18S rRNA genes by fluorescence in site hybridization (FISH). C-banding and Ag-staining were also performed to analyse whether variation in heterochromatin and Ag-nucleolus organizer regions (NORs) exists among various commercially purchased strains. The results provide information on heterochromatin composition and on the existence of interindividual NOR polymorphism and contribute to the construction of an idiogram suitable for gene mapping.
