| Description
| - 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 specimens from ele...

- Byla analyzována chromozómová evoluce u afrického halančíka Chromaphyosemion bivittatum použitím kombinace cytogenetických a fylogenetických metod. Cytogenetická analýza ukázala varaibilitu 2n od 29 do 36 chromozómů a NF od 38 do 44. Dvě populace byly extrémně polymorfní ( 2n = 29 - 34, NF = 44 a 2n = 32 - 34, NF = 38 - 42). Karyotypová variabilita uvnitř a mezi populacemi byla způsobena ponejvíce Robertsonovskými transkolakacemi a heterochromatinovými adicemi, kde oba typy přestaveb byly asociovány s AT-specifckým heterochromatinem. fylogenetická analýza ukázala velmi nízkou úroveň genetické diferenciace a ukazuje na velkou rychlost chromozomové evoluce.
