Do all the Fantasy horned frogs have not the fertility?

[Namio]

We all know the fantasy horned frogs come from cranwellic and ornata, but i want to know more about their chromosome, and the fertility of fantasy frogs

Perhaps you made a typo, but I believe Fantasy frogs came from Cranwelli and Cornuta.
A hybrid from Cranwelli and Ornata produces another type (Orwell), which is completely different from Fantasy.
Someone else can probably tell you more about chromosome differences but Fantasy frogs are known to be infertile. Although it doesn't mean that they're all infertile, there' not one instance of fertile Fantasy that I have ever heard of.
