Polymorphism and interpopulation variability of the karyotype in the Caspian bighead goby Neogobius gorlap (Gobiidae, Perciformes)

Chromosome polymorphism has been for the first time found in the Caspian bighead goby Neogobius gorlap . Eleven karyomorphs have been found in four populations under consideration. The number of chromosomes varied from 43 to 46, the number of chromosome arms is 46. Interpopulation variabilities in t...

Description
Summary:Chromosome polymorphism has been for the first time found in the Caspian bighead goby Neogobius gorlap . Eleven karyomorphs have been found in four populations under consideration. The number of chromosomes varied from 43 to 46, the number of chromosome arms is 46. Interpopulation variabilities in the mode of polymorphism, possible chromosome mutations leading to the polymorphism, and possible sources of the polymorphism in different populations have been discussed.
