Název v původním jazyce

Karyotype differentiation in Chromaphyosemion killfishes (Cyprinodontiformes, Nothobranchiidae). I: Chromosome banding patterns of C. alpha, C. kouamense and C. lugens

Popis výsledku v původním jazyce

The karyotypes of three recently described species of Chromaphyosemion, namely C. lugens, C. aplha and C. kouamense, were analysed using conventional Giemsa standing, C-banding and sequential banding. Diploid chromosome numbers ranged from 2n=36 in C. lugens to 2n=38 in C. alpha and C. kouamense. The karyotype of C. lugens consisted of one pair of metacentric (m) and 17 pairs of telocentric (t) chromosomes, that of C. alpha was composed one of pair of submetacentric (sm), six pair of subtelocenric (st)and 12 pairs of t chromosomes, and that of C. kouamense comprised five pairs of st and 14 pairs of t chromosomes. In addition to the differences in karyotype structures and/or chromosome numbers, the karyotypes of the examined species differed with respect to NOR phenotype and distribution and base composition of heterochromatin. No heteromorphic sex chromosomes were detected in any of the species.
