Hi
I was wondering if anyone knows how many generations of young can be bred from a single pair of lizards before the offspring become infertile or problems occur when bred with each other ? Does anyone rotate their males and females each spring to give a more diverse gene pool ? How would this be overcome in the wild ?
cheers chris

Hi Chris,
How many generations have you got to with yours on a single pair?

If you can rotate your animals or bring in fresh blood it will be better for your colony. Although I would not worry too much about inbreeding in lizards. Look at the morph hobby in Leopard Geckos and Royal Pythons. Closely related animals are often bred together to create a new morph but for the most part are fine. You may notice that there will not be as much genetic variation in subsequent young.
What species are you worried about?

Hi Virdis,
My animals are Billineata, I have been breeding the same pair but have other males and females which I could rotate around different cages next year. They are comfortable in their cages and I'm wary to disturb them. I was wondering what if anything other people do.

pogona vitticeps can have some negative effects from inbreeding. Curly tailed hatchlings and smaller hatchlings occur, and perhaps lower fertility. I'm not sure how many generations it takes for these to start to show, but they will. Presumably it is similar for other lizards. Rotation, careful selection of breeders, and occasional new blood are the way I manage mine.
