Clone : A clone is what you make of the Genes Framework. Every url-reached folder with an index.php that includes the framework is a different clone. With custom config file.

Comps : Comp is short for Genes components, like small bundles of functional UI components.
I hate including tens of js and css files so the core UI framework includes most of the widely used components.

Mods : Mod is a modification of Genes, like a plugin, or a bundle of backend code focused on a function. Every clone is unique in its own way, mods are included to add some features and functionality to the clone.
