Karyotypes of two Antarctic fishes, Notothenia gibberifrons and Notothenia coriiceps neglecta

The chromosomes of two species of Antarctic fishes, Notothenia (Gobionotothen) gibberifrons and Notothenia (Notothenia) coriiceps neglecta, were prepared by the air-drying method at the Polish Antarctic Station “Henryk Arctowski” during the austral summer 1984-1985. For N.(G.) gibberifrons the diplo...

More Information
Summary:The chromosomes of two species of Antarctic fishes, Notothenia (Gobionotothen) gibberifrons and Notothenia (Notothenia) coriiceps neglecta, were prepared by the air-drying method at the Polish Antarctic Station “Henryk Arctowski” during the austral summer 1984-1985. For N.(G.) gibberifrons the diploid number is 2n=46 consisting of 2 metacentric (m) pairs, 1submetacentric (sm) pair and 20 telocentric (t) or subtelocentric (st) pairs. For N.(N.) coriiceps neglecta the diploid number is 2n=22 consisting of 9 m pairs, 1 sm pair and 1st pair. Some aspects of karyological evolution of these fishes are discussed.
