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). adj., adj parthenogenet´ic.
Did you know several species of reptile and amphibian are parthenogenetic? Most reptiles reproduce sexually, but parthenogenesis has been observed to occur naturally in certain species of whiptails, geckos, rock lizards, blindsnakes, Komodo dragons and boa constrictors.  There is also a debate on whether Giant New Caledonian geckos (Rhacodactylus leachianus) are parthenogenetic since some owners have reported offspring from non fertilized eggs.
