X breeding

[esmoot]

Just one quick question. I have always heard that crossbreeding is possible but the offspring will be infirtle. Is this true or not?

If it is true crossbreeding still could be a small problem if the t's were sold but they could never reproduce. So you would always have only 1 generation that could not pollute the gene pool.

There's the question of variations within species.

If different species crossbreed and produce infertile offspring then they are, indeed, different species, perhaps capable of the act of reproduction, but incapable of continuing the bloodline. If they are able to cross-breed and produce fertile offspring, and so on and so on, then IMO they must be a variation of the same species. Not sure if that answers your question or not?

I can't find it right now.... going nuts. I saw, on a dealer's price list, a brachypelma cross, I think it was vagans and something else, but yes, they were ACTUALLY selling them to the public!!! It's being done, and it's STUPID, STUPID, STUPID!!!

Next time you buy a T, ask yourself if you're 100% ABSOLUTELY POSITIVELY SURE that it's "PURE"!!

Yes even if you produce infirtile offspring they would be a different sp. but since the offspring are always infiritle(from what I'm told) where is the problem?

The problem really is that a successful breeding resulting in fertile offspring of what was previously thought to be separate species would throw taxonomy into chaos and have the taxonomists beating their heads against their tables. Things is tarantula breeding (as far as hybridizing) hasn't been attempted on a large enough scale or for long enough to determine if/which species can/will produce fertile offspring or not. Some fear actual fertile offspring could leak into the hobby and possibly defile the bloodlines of purebred species.

I understand that totally but it has not happend as far as I know. If it is proven possibe then there is a problem. I understand that crossbreeding is quite regular in Germany.
