Karyotype differentiation in Chromaphyosemion killifishes (Cyprinodontiformes, Nothobranchiidae) III: Extensive karyotypic variability associated with low mitochondrial haplotype differentiation in C. bivittatum

Popis výsledku v původním jazyce

We investigated chromosomal evolution in the African killifish species Chromaphyosemion bivittatum using a combination of cytogenetic and phylogenetic methods. Specimens from five populations were examined by conventional Giemsa staining as well as sequential chromosome banding with 4', 6-diamidino-2-phenylindole (DAPI), chromomycin A 3 (CMA(3)), AgNO3-staining and C-banding. The cytogenetic analysis revealed variability in 2n ranging from 2n = 29 to 2n = 36 and in NF ranging from NF = 38 to NF = 44. Two populations showed an extensive chromosomal polymorphism ( 2n = 29 - 34, NF = 44 and 2n = 32 - 34, NF = 38 - 42, respectively). Karyotypic variability within and among populations was mainly due to Robertsonian translocations and heterochromatin additions, and chromosome banding patterns suggested that both types of chromosomal rearrangements were related to the presence of AT-rich heterochromatin. A phylogenetic analysis of the partial mitochondrial (mt) cytochrome b gene, using speci
