Zusammenfassung

Aus Erythrozytenkernen von TritonTriturus pyrrhogaster und von KarauscheCyprinus auratus werden die spiralen, metabolischen Chromosomen gewonnen. In den Leukozytenkernen aus KaninchenOryctolagus cuniculus var.domesticus lassen sich zwei Arten von Chromosomen hinsichtlich der Strukturen feststellen: Spiraler Typus (Autosom) und flagellumartiger Typus (Geschlechtschromosom). Bei den Chromosomen des spiralen Typus ist die Doppelnatur der Schraubenwindungen der Chromonemata erkennbar. Es ist wahrscheinlich, dass die grossen Spiralen nach rechts, jedoch die kleinen nach links ranken. Das metabolische Geschlechtschromosom besteht aus einem kompakten, undurchsichtigen Teil, einem schwach durchsichtigen, fadenartigen Teil und einem kleinen, völlig undurchsichtigen Endstück.
