    Default Retained sperm and parthenogenisis

    Just curious to this in leopard geckos, as I've been talking about it a lot with ball python breeders on my other forum. Female ball pythons can retain sperm for 1-3 breeding seasons and 'choose' when to use it even if bred to a new male with different genetics. (No idea how they know lol). But there is also a small number of virgin ball pythons that self fertilize their ovum and lay fertile eggs - the hatchlings are all identical twins, but not clones of the mother - when they have never been with a male or even in the same household as one.

    Is sperm retention or parthenogenesis something that is seen in leos?
    Just curious

    I have never heard of parthenogenesis in leopard geckos though it does happen in leachianus geckos, crested geckos and gargoyle geckos. Leopard geckos, like most geckos, do retain sperm though I have never heard of a documented situation where they were able to do that from one breeding season to the next.
    On the other hand, I had a bearded dragon many years ago that had not been with a male for at least 4 years (and I'm not sure whether or not she was before that) who laid an egg that yielded a fully formed hatchling which did not live to exit the egg. I had never heard of this in bearded dragons either.
