How do I sell Genesis Child Themes on ThemeForest?

I've been struggling with all these licences and stuff, I need some serious help. I want to sell Genesis Child Themes on Themeforest, is this even possible? If so I do have some additional questions:

1) Can I simply include Genesis in my .zip file and just be?

2) If not, do I need to inform potential buyers about purchasing another framework? That kinda makes all the sales impossible.

3) And if so, where should I sell these themes instead?

Thanks a lot.
