Parthenogenesis is the spontaneous development of an embryo from an unfertilized egg cell. It naturally occurs in a variety of plant and animal species. In plants, parthenogenesis usually is found in combination with apomeiosis (the omission of meiosis) and pseudogamous or autonomous (with or without central cell fertilization) endosperm.

Abstract. Contagious parthenogenesis-a process involving rare functional males produced by a parthenogenetic lineage which mate with coexisting sexual females resulting in fertile parthenogenetic offspring-is one of the most striking mechanisms responsible for the generation of new parthenogenetic lineages.

Natural Parthenogenesis.

Generally, an egg cell and a sperm cell are required for sexual reproduction.

Parthenogenesis is a form of asexual reproduction by self-impregnation resulting in the production of a zygote from an unfertilized egg. Thus, it is also referred to by many as "virgin birth" . Parthenogenesis takes place in both asexual animals and plants. In animals, the embryo develops from an unfertilized egg.
