In order to prove the possibility that horizontal gene transfer can take place through interspecies hybridisation in lower eukaryotes, we showed that the hybrids contained complete genomes from the hybridising species but their alloploid genomes were unstable and prone to undergo segregation. In the analysis we used classical methods (assimilation and fermentation tests, random spore analysis) and molecular methods (PCR-RFLP and electrophoretic karyotyping).34enhybridisationSaccharomycesDEENK Témalista::Biológiai tudományok::Molekuláris biológiaDEENK Témalista::Biológiai tudományok::Genetika
