  1. parthenogenesis (pär'thənōjĕn`əsĭs) [Gr.,=virgin birth], in biology, a form of reproduction in which the ovum develops into a new individual without fertilization. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g., the aphid aphid or plant louse, tiny, usually green, soft-bodied, pear-shaped insect injurious.
  2. May 27,  · Parthenogenesis, translated from its Greek word origins, means virgin birth. The process — which is more common in the plant and insect worlds — allows a female organism to replicate itself.
  3. Oct 10,  · Parthenogenesis is a natural type of asexual reproduction that is quite common in invertebrates and lower plants. Parthenogenesis means the development and growth of embryos from unfertilized eggs. Parthenogenesis occurs in plants through draditalcudlerasorelolensiri.coinfo: Geoffrey Migiro.
  4. Apr 21,  · In parthenogenesis, the egg becomes the sole source of genetic material for the creation of an embryo. It is a mode of reproduction in some species, though not in mammals. In mammals.
  5. parthenogenesis [pahr″thĕ-no-jen´ĕ-sis] a modified form of sexual reproduction in which a gamete develops into a new individual without the fertilization of an oocyte by a spermatozoon, as in certain arthropods and other animals; it may occur as a natural phenomenon or be induced by chemical or mechanical stimulation (artificial parthenogenesis.
  6. Parthenogenesis – development of an unfertilised female sex cell without any male contribution – is a normal way of life for some plants, insects and even lizards. Sometimes, an unfertilised.
  7. Parthenogenesis is the development of an unfertilized egg into a new individual. Coined by Carl Theodor Ernst von Siebold (b. –d. ) in , the literal meaning of parthenogenesis is “virgin reproduction”—reproduction in the absence of males.
