Is an underbite beak a genetic trait?

[riverman]

I just noticed today my 7 month old BLRW Roo has a underbite!!! I've been hatching a couple chicks from him and got rid of my other BLRW Roo's already. Is there a chance his offspring can have an underbite beak as well?

The more I study genetics, the more I've come to realize that most things are genetic. So if it's truly an underbite and not caused by injury, then I would say yes. My experience is with dogs, sheep and finches, in those cases it's an inherited trait.
