Among the fish which were cytogenetically studied, most of them do not possess any morphologically differentiated sex chromosomes. On the other hand, karyotypic analysis, chromosome binding, synaptonemal complex observation and comparative genomic hybridization show in few fish species, that there exist sex chromosomes which differentiated at different levels and types.
