Abstracts

EN

Chromosome banding studies were performed in vendace, Coregonus albula. Original data on distribution of early and late replication regions, restriction sites (AluI, DdeI, HinfI and HaeIII) on chromosomes in this coregonid fish have been used to analyse karyotype heterochromatin differentiation. Heterochromatic bands (C-positive and not digested by restriction enzymes) have been identified as late replicating regions. Extra bands produced by the applied methods have permitted the identification of several homologous pairs. The centromeres were differentially digested by the restriction enzymes. The studied population seems to be homogenic regarding karyotype characteristics.
