摘要: Summary The genet of clonal plants is currently defined as the genetic individual that develops from zygote and produces ramets vegetatively. Genetic individuality refers to fact it considered be a genetically uniform plant. However, somatic mutations may give rise mosaics within genet, invalidating assumption its uniformity. On other hand, zygotes are not only initial cells genets, since parthenogenetic female gametes also develop into new individuals directly. Sexual asexual types reproduction similar in terms dispersal, dormancy, recruitment, seedling development, especially compared with vegetative fragmentation, process does create genets. For autotrophic macroorganisms, such bryophytes red seaweeds, result variety spores, zygotes. These considerations suggest existing definition should updated. general, free-living one original zygote, gamete, or spore vegetatively during growth. degree differentiation between consecutive generations genets will primarily depend on type involved. Der Genet klonaler Pflanzen ist definiert als das genetische Individuum sich aus einer Zygote entwickelt und auf Weise Rameten produziert. Begriff der genetischen Individualitat besagt, dass genetisch homogen ist. Jedoch konnen somatische Mutationen innerhalb des Genets dazu fuhren, ein genetisches Mosaik entwickelt, die Organismus verletzt. Andererseits Geneten nicht nur Zygoten entwickeln, aber auch parthenogenetisch von weiblichen Gameten abstammen. Sexuelle asexuelle Fortpflanzung gleichen einander Verbreitung, Ruhezustand, Rekrutierung, Keimlingsentwicklung, speziell verglichen mit vegetativer Fragmentation, einem Prozess bei dem keine neuen entwickeln. Neue Individuen anderen klonalen, autotrophen Makroorganismen wie klonale Bryophyten Rotalgen entwickeln Vielfalt Sporen, Zygoten. In dieser Hinsicht sollte Definition fur autotrophe aktualisiert werden. Generell kann freilebende werden, Zygote, parthenogenetischen oder Spore Grad Differenzierung zwischen konsekutiven Generationen hangt primar Reproduktionsart ab.
