Parthenogenesis

n. reproduction by the development of an unfertilized egg

Parthenogenesis (from the Greek παρθένος parthenos, "virgin", + γένεσις genesis, "creation") is an asexual form of reproduction found in females where growth and development of an embryo or seed occurs without fertilization by males. Parthenogenesis occurs naturally in some species, including most lower plants, a Kalanchoe succulent plant genus of South Africa, invertebrates (e.g. water fleas, aphids, some bees, some scorpion species, and parasitic wasps), and vertebrates (e.g. some  reptiles, fish, and, very rarely, birds and sharks) and this type of reproduction has been induced artificially in other species.
