Figure_8 Posted January 18, 2006 Report Share Posted January 18, 2006 A discussion on parthenogenic fish in the Betta Splendens forum inspired me to do a little searching. There is a fish in the Amazon that basically clones itself without the genetic input of a male! I found this article very interesting, so I thought I'd share. http://home.clara.net/xenotoca/amazon.htm Link to comment Share on other sites More sharing options...
splendidbetta Posted January 18, 2006 Report Share Posted January 18, 2006 How about fish that start off one sex and change when they mature or according to the species sex ratio? I tried looking for the place I found that parthenogenic betta, but I couldn't find it. I couldn't find anything on google either. :) Link to comment Share on other sites More sharing options...
Callatya Posted January 24, 2006 Report Share Posted January 24, 2006 I've heard that there are some snails that can do this too, but apparently there are several ways of having one parent produce the offspring. All sounds like good survival skills to me! Link to comment Share on other sites More sharing options...
Daniel Posted January 25, 2006 Report Share Posted January 25, 2006 although not fish, some other animals have the ability to change sexes, some frogs i cant name them off the top of my head, turn male when there is no male population, if you recall jurassic park, where they took the dna form a misquito preserved in amber and used those genes as well as some form a frog to produce dinosaurs (they used the frogs dna to fill in the missing parts or something) the frogs they used have the same characteristic and they enabled them to breed.... just a thought heres a link parthenogenesis it also talks about gynogenesis and hybridogenesis Link to comment Share on other sites More sharing options...
dpeica Posted January 25, 2006 Report Share Posted January 25, 2006 A couple of native reptiles are capable of it too. Some races of Bynoe's prickly gecko (Heteronotia Binoei) and some species of blind snake (Ramphotoyphlops sp) come to mind. Link to comment Share on other sites More sharing options...
