  • Title: Cytogenetic characteristics of the fish genus Cobitis from England.
    Author: Boroń A, Culling M, Pułym A.
    Journal: Folia Biol (Krakow); 2003; 51 Suppl():13-6. PubMed ID: 15303333.
    Abstract:
    The chromosomes of spiny loach specimens, genus Cobitis, from three populations in England were examined using Giemsa staining, Ag-NOR, C-banding and CMA3 techniques. All individuals examined invariably had a diploid chromosome number 2n=48 and a karyotype composed of ten metacentric, eighteen submetacentric and twenty subtelo-acrocentric chromosomes. The results revealed that only C. taenia occurred in the northern part of the Cobitis distribution range. Various cytogenetic features such as the number and location of Ag-NORs, DNA sites rich in GC pairs, and C bands confirmed the taxonomic status of the specimens. Among the individuals from English populations no polyploid forms have been detected.
