I never knew the word and the meaning thereof parthenogenesis' till yester-eve.

Parthenogenesis is a type of asexual reproduction in which a female gamete or egg cell develops into an individual without fertilization. Animals including most kinds of wasps, bees, and ants that have no sex chromosomes reproduce by this process. Some reptiles and fish are also capable of reproducing in this manner. Many plants are also capable of reproducing by parthenogenesis.

Most organisms that reproduce by parthenogenesis also reproduce sexually. This type of parthenogenesis is known as facultative parthenogenesis and organisms including water fleas, crayfish, snakes, sharks, and Komodo dragons reproduce in this manner. Other parthenogenic species, including some reptiles, amphibians, and fishes, are only capable of reproducing asexually.

Parthenogenesis is an adaptive strategy to ensure the reproduction of organisms when conditions are not favorable for sexual reproduction. Asexual reproduction can be advantageous to organisms that must remain in a particular environment and in places where mates are scarce. Numerous offspring can be produced without "costing" the parent a great amount of energy or time. A disadvantage of this type of reproduction is the lack of genetic variation. There is no movement of genes from one population to another. Due to the fact that environments are unstable, populations that are genetically variable will be able to adapt to changing conditions better than those that lack genetic variation.

Isn't it strange?

You start some very interesting threads, Ashwin Joshi.

Do you think humans will ever be able to accomplish that? Whistle

Hello Boneyfriend, a rare visitor these days!

Thanks for the article, Ashwin, very interesting.

On human parthenogenesis, Hope, you may find this novella interesting - it's by the author who wrote 'Day of the Triffids'.

I just checked and my library has the trilogy but not the "Consider Her Ways". I've never read the trilogy - I could do that for something different. :) That is not usually my genre.

Hi Boneyfriend, I flowed into TFD Forum in your transient time off which, I am sure must be for some bigger noble cause.I am a learner. One's brain becomes fertile in the company of nice, lovely and intelligent personalities. Hence I joined this forum.Still, a lot remains to be learnt.

I wish TF-Dears could have a converge as a world family. Won't it be great, worth and enjoyable?

Parthenogenesis and Metamorphosis first sparked my interest in biology and both continue to blow my mind to this day. Truly fascinating stuff. Applause
