Strain??

So I got just a seed from a friend,, have no idea what it is. He indicated to me that it is probably “white rhino” or “ak47”.
Is there a noticeable difference in these strains that someone can identify. She is about 4 weeks into flower and I know it is week, since I have a cheap amazon light for now. But wondering if there is a way to identify

Look at a bunch of pictures of each then make your best guess. Or get it genetically tested.
