Abstract:Published data on chromosome numbers of Salmonoidei are summarized. The existence of homologous variation of chromosome number in different phyletic lines of this suborder is substantiated. It is suggested that the origin of homologous series is related to major genome rearrangements (simultaneous fusion of several chromosomes).
