  Die ungeschlechtliche oder monogene Zeugung (Monogonie) ist dadurch charakterisirt, dass das Wachsthumsproduct des elterlichen Organismus selbstständig entwickelungsfähig ist, ohne der Befruchtung, der Vermischung mit einem anderen Wachsthumsproducte zu bedürfen.

  Most of my readers probably only know those phenomena of Propagation which are seen universally in the higher plants and animals, the processes of Sexual Propagation, or Amphigony. The processes of Non-sexual Propagation, or Monogony, are much less generally known. The latter, however, are far more suited to throw light upon the nature of transmission by inheritance in connection with propagation.
