| Description
| - V práci jsou sledovány tři druhy jeseterovitých ryb (Acipenser ruthenus, A.gueldenstaedti a A. baerii) z hlediska jejich genetické čistoty. Analýzou DNA pomocí průtokové cytometrie a pomocí rozměrů jader erytrocytů stanovených analýzou obrazu bylo zjištěno, že pouze A. ruthenus je čistý tetraploid v 93,33%, zatímco A. gueldenstaedti a A. baerii jsou hexaploidní. Byla stanovena hypotéza, že hexaploidní jedinci jsou F1 mezidruhovými hybridy tetra a oktaploidních druhů jeseterů, zatímco pentaploidní jedinci mohou pocházet z křížení F1 hybridů s tetraploidními rodiči v akvakulturních chovech a heptaploidní jedinci pocházejí z podobného křížení F1 hybridů s oktaploidními rodiči.

- Three presumably purebred aquaculture stocks of sturgeons (Acipenser ruthenus, A. gueldenstaedtii and A. baerii) were investigated. Analyses of DNA contents by flow cytometry and of erythrocyte nuclear dimensions by microscope-coupled, computer-assisted image analysis revealed that only an A. ruthenus stock was purebred tetraploid in 93.33%; whereas both A. gueldenstaedtii and A. baerii stocks under study consisted of hexaploids, yet unknown penta- or heptaploid specimens and purebred octaploids. We hypothesized that the hexaploid specimens were F1 interspecific hybrids of tetra- and octaploid sturgeon species, whereas pentaploid specimens may have originated from an intentional or accidental backcross of the F1 hybrid to tetraploid parental species in aquaculture, and the heptaploid specimens may have originated from similar backcross of the F1 hybrid to octaploid parent.
