Questions on usage of and, comma, apostrophe

Can and be followed by a comma? Is this a tested concept in GMAT? If so, Is this wrong gramatically?

What is the difference between ape's and apes'?

Does which need to be preceded by a comma?

Thanks

Hey guys - we are a bit behind right now but, even when we're not behind, it's rare to get an answer in one day. :) Three days is more common. (And a week isn't uncommon during very busy times, such as now.)

The word "and" can definitely be followed by a comma:
She prefers cooking to eating out and, although she has no formal training, she is an excellent cook.

Typically, if you have a comma right after "and," you have some kind of little "aside" sort of interrupting the sentence for a few words. It is not tested on the GMAT.

ape's and apes' are both possessive, but the first is singular (one ape's fur, for example) and the second is plural (four apes' fur, for example).

Which is typically preceded by a comma, yes, though this isn't typically tested on the GMAT. (In general, they don't test us simply on comma placement.)
