A young Komodo dragon, Varanus komodoensis, produced through parthenogenesis. Komodo dragons can produce offspring both through sexual reproduction and parthenogenesis. Parthenogenesis is a form of asexual reproduction in which the embryo develops directly from an egg without need for fertilization.
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards). [1]
Parthenogenesis in insects can cover a wide range of mechanisms. [11] The offspring produced by parthenogenesis may be of both sexes, only female (thelytoky, e.g., aphids and some hymenopterans [12]) or only male (arrhenotoky, e.g., most hymenopterans).
The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” ... Females of species have the ability to reproduce asexually, without sperm from a male. The process ...
Honey bees produce haploid males from unfertilized eggs. Arrhenotoky (from Greek ἄρρην árrhēn "male" and τόκος tókos "birth"), also known as arrhenotokous parthenogenesis, is a form of parthenogenesis in which unfertilized eggs develop into males. In most cases, parthenogenesis produces exclusively female offspring, hence the ...
This can be due to parthenogenesis, ... occurs as separate male or female individuals that produce male and female gametes respectively.
There are many animals that can give birth by parthenogenesis, according to National Geographic. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish ...
However, in gonochoric species individuals remain either male or female throughout their lives. [4] Species that reproduce by thelytokous parthenogenesis and do not have males can still be classified as gonochoric. [5] [clarification needed]
