No, but many aspects are similar. The source editors are very similar, but Wikia and Wikipedia have some different additional features available in the dedicated source editor (Wikia has coloring and category select), for example). The Visual editors also diverge in features.

They have templates with similar names, but how they work can be completely different in the same way many different Wikia wikis have the same template names, but they look and function very differently.

You'll just have to experiment. Lastly, you should be posting this question somewhere on Wikipedia, if that's where you're working.
