Abstract
The karyotype of Zingel zingel from the Morava River (Czech Republic) was analyzed. The diploid chromosome number was 2n=48 in females and 2n=47 in males, however, one large unpaired metacentric chromosome was present in males. This proves to be the X1X1X2X2/X1X2Y multiple sex chromosome system developed from the fusion of two sub- or acrocentric chromosomes where a sex chromosome Y was present as one of them. © 2007 Taylor and Francis Group, LLC.
