APAKAH MAKSUD PARTHENOGENESIS dalam CORSICA?
Parthenogenesis
Parthenogenesis / ˌpɑrθənoʊdʒɛnəsɨs / adalah sejenis pembiakan aseksual di mana pertumbuhan dan perkembangan embrio berlaku tanpa persenyawaan. Dalam haiwan, parthenogenesis bermakna perkembangan embrio dari sel telur yang tidak diserap dan merupakan proses komponen apomixis. Gynogenesis dan pseudogamy adalah fenomena yang berkait rapat di mana sperma atau debunga mencetuskan perkembangan sel telur menjadi embrio tetapi tidak memberikan sumbangan genetik kepada embrio. Selebihnya sitologi dan genetik fenomena ini kebanyakannya sama dengan parthenogenesis. Perkataan parthenogenesis berasal dari bahasa Yunani παρθένος, parthenos, yang bermaksud "dara" dan γένεσις, genesis, yang bermaksud "kelahiran". Istilah ini kadang-kadang digunakan secara tidak tepat untuk menggambarkan mod reproduksi dalam spesies hermaphroditic yang dapat membiak sendiri kerana ia mengandung organ-organ pembiakan kedua-dua jantina dalam tubuh tunggal individu. Parthenogenesis berlaku secara semulajadi di banyak tumbuhan, beberapa spesies binatang invertebrata dan beberapa vertebrata. Jenis pembiakan ini telah diakibatkan artifak dalam beberapa spesies termasuk ikan dan amfibia.

Biology: A Functional Approach
Parthenogenesis is the development of a new individual from an unfertilized egg.
Although many instances of artificial parthenogenesis are claimed, as a natural
occurrence it is restricted to certain groups of invertebrates, notably insects.
Virgin birth Most eggs lie dormant and eventually die unless they are roused into
new development by a sperm, but a minority of eggs can accomplish this feat on
their own accord. Virgin birth — or parthenogenesis — is now causing a flurry of ...
Introduction Parthenogenesis is a form of reproduction in which an egg can
develop into an embryo without being fertilized by a sperm. Parthenogenesis is
derived from the Greek words for "virgin birth," and several insect species
