Do all the Fantasy horned frogs have not the fertility?

[Iragil]

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.

Namio is right. A Fantasy Frog is produced by breeding a Cranwelli to a Cornuta and the product of a Cranwelli and Ornata is an Orwell. Orwells are extremely rare and it very unlikely you'll find one. Almost all hybrids are considered infertile and a lot of them excluding the Fantasy don't survive long enough to reach sexual maturity to attempt breeding because the pairing of certain species produce frogs with genetic malformations and weakened immune systems. The key example of this genetic issue is the Green Apple Pacman which is the product of C. Cranwelli and C. Joazeirensis(Caatinga). Almost no Apples survive to adulthood.

I don't know much about genetics, but I believe the Cranwelli are diploid and Ornatas are octaploid. I don't remember off the top of my head what the Cornuta is...
