    Morphological (meristic and morphometric traits), karyological and molecular (microsatellites, cytochrome b) analyses were performed to characterize a hybrid of the roach Rutilus rutilus and nase Chondrostoma nasus. Meristic and morphometric traits were different between hybrid and both parental species. The number of chromosomes found in hybrid specimen indicated that this individual represents the post-F1 generation of hybrids and the microsatellite analysis of the hybrid showed the presence of variants typical for R. rutilus and C. nasus.

    Morfologické (meristické a morfometrické znaky), karyologické a molekulární (mikrosatelity, cytochrom b) charakteristiky byly provedeny k rozlišení hybridního jedince mezi Rutilus rutilus a Chondrostoma nasus. Meristické a morfometrické znaky byly odlišné mezi hybridem a rodičovskými druhy. Počet chromozomů u hybridního jedince naznačuje, že se jedná o post-F1 generaci hybridů. Mikrosatelitová analýza hybrida potvrdila varianty typické pro R. rutilus a C. nasus.
