    Identification of a new reciprocal translocation Y t(2;4)(q45;q34) in an AI bull of Ayrshire breed, with the use of synaptonemal complex technique and chromosome painting

  • Original language description

    An AI Ayrshire bull was subjected to cytogenetic examination due to lowered fertility. Preliminary Giemsa staining revealed a normal chromosome complement (60,XY) and G-banding did not allow us to draw a clear conclusion concerning an occurrence of chromosome rearrangement. Testicles were collected at slaughter and synaptonemal complex (SC) analysis revealed a large cross-shaped tetravalent configuration in pachytene spreads. No association between the tetravalent and XY bivalent was observed. Chromosome painting, with the use of bovine whole chromosome painting probes, conjugated with DAPI staining, facilitated a detailed description of the translocation rcp(2;4)(q45;q34). This study shows that post mortem analysis of synaptonemal complexes is a simple and useful tool for the preliminary detection of reciprocal translocation carriers.

    Identifikace nové reciproké translokace Y t(2;4)(q45;q34) u býka of Ayrshirského plemene využitím analýzy synaptonemálních komplexů a paintingových sond

  • Czech description

    U býka Ayrshirského plemene bylo provedeno cytogenetické vyšetření z důvodu jeho snížené fertility. Po barvení Giemsou byl zjištěný normální karyotyp (60,XY) and G-pruhování neodhalilo žádnou chromozomální přestavbu. Po porážce byla odebrána varlata, analýza synaptonemálních komplexů odhalila velký tetravalent v pachytenních buňkách. Žádné spojení mezi tetravalentem a XY bivalentem nebylo pozorováno. Hybridizace s chromozom-specifickými paintingovými sondami umožnila detailní popis translokace rcp(2;4)(q45;q34). Studie ukázala, že post mortem analýza synaptonemálního kompexu je jednoduchá a užitečná metoda pro předběžnou detekci nosičů reciproké translokace.
