ABSTRACT
Analysis of metaphases of Palaemon serratus (Pennant, 1777) revealed a diploid number of In = 56 chromosomes with a karyotype composed of two large metacentric pairs, six subtelocentric pairs and twenty telocentric pairs. Four Ag-NORs and 45S rDNA signals were observed at the telomeres of two small telocentric chromosome pairs. Chromomycin A3 fluorochrome staining revealed GC-rich regions associated with Ag-NORs, and DAPI showed positive bright bands on centromeric or intercalary positions of subtelocentric and telocentric chromosomes.
