Highly dynamic sex chromosomes in cichlid fishes

The cichlids of Lake Tanganyika in Africa are highly diverse – including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, depending on the species, can be of the type XY or ZW. This has been reported by a research team from the University of Basel and the Research Museum Koenig in Bonn in the scientific journal Science Advances.
