In the case of many insects in which parthenogenesis occurs, the determination of sex depends upon fertilisation.
I have dealt with the physiology of parthenogenesis in the seventeenth chapter of the Riddle.
How far this may extend in the direction of more mature development is shown by what is known about parthenogenesis.
Sex-generation is the mark of a higher organism than parthenogenesis.
There are some interesting remarks on this brilliant generalization in Owen's parthenogenesis, 1849, pp. 53 seq.
parthenogenesis is no longer wonderful; in fact, the wonder is that it should not oftener occur.
parthenogenesis occurs; the unfertilized eggs produced only males (Flock, 1941).
Is it true that female Primula plants always produce females by parthenogenesis?
parthenogenesis without heterogamy occurs in a large number of forms.
The same tendency reaches its logical conclusion in the parthenogenesis of insects.
parthenogenesis par·the·no·gen·e·sis (pär'thə-nō-jěn'ĭ-sĭs)
A form of reproduction in which an unfertilized egg develops into a new individual, occurring commonly among insects and certain other arthropods.
Reproduction in which an egg develops into a new individual without being fertilized. Aphids and certain other insects can reproduce by parthenogenesis. Parthenogenesis does not necessarily produce clones of the parent. Among hymenopterans such as honeybees and ants, the haploid males develop from unfertilized eggs laid by the queen, who is diploid. Parthenogenesis is a form of apomixis.
