Parthenogenesis (Apomixis)

It is the development of a new individual from a single gamete (generally the egg/ovum) without involving fertilisation. On the basis of chromosomes sets, parthenogenesis is of two types (i) Arrhenotoky (haploid) parthenogenesis). Haploid eggs grow to form haploid males  arachnids, some insects. (ii) Thelytoky (diploid parthenogenesis). Diploid eggs grow without fertilisation into diploid individuals, generally females  Gall fly. Parthenogenesis can be natural or artificial. Natural parthenogenesis may be obligatory or cyclic.

Obligatory/Complete Parthenogenesis Males are absent. Females develop parthenogenesis,  rotifers, Typhlina brahmina (small lizard, 15 cm long), Lacerta saxicola armeniaca (caucasian rock lizard), Cnemidophorus (whiptail lizards of America).

Cyclic/Incomplete Parthenogenesis Both sexual and parthenogenetic individuals occur. In aphids several generations of parthenogenetic females develop followed by formation of both male and females to perform sexual reproduction. In Turkey, 40% of the males develop parthenogenetically. In honeybee, male of drone develops parthenogenetically (no meiosis at the time of spermatogenesis) while queen and workers develop from fertilized eggs. Also in wasps and ants. In gall fly, larvae may lay eggs that develop parthenogenetically (paedogenesis)
