KARYOLOGICAL STUDY OF THE MEDITERRANEAN KRILL MEGANYCTIPHANES-NORVEGICA (EUPHAUSIACEA)
The chromosomes of Meganyctiphanes norvegica from the Mediterranean Ligurian Sea were investigated using standard Giemsa, silver staining, and C-banding. The karyotype of both sexes consists of 19 metacentric chromosome pairs of gradually decreasing size. Silver staining of male mitotic and meiotic...

The chromosomes of Meganyctiphanes norvegica from the Mediterranean Ligurian Sea were investigated using standard Giemsa, silver staining, and C-banding. The karyotype of both sexes consists of 19 metacentric chromosome pairs of gradually decreasing size. Silver staining of male mitotic and meiotic metaphase showed, in all chromosomes, centromeric regions that appeared to be related to kinetochores rather than to nucleous-organizer regions. C-banding revealed centromeric constitutive heterochromatin in all chromosomes. No heteromorphic sex differentiation was observed. The karyotype of the krill Meganyctiphanes norvegica is reported here for the first time and will provide a basis for further cytogenetic investigation of species and populations of krill. |
