Cut it in half and count the rings.
Yes. You can tell if your gerbil is scared if he shivers or if he chatters his teeth

Look on his back side. If it is a Female there are no lumps, the gaps between each ahem holes are larger on a male and smaller one a female. also it is like a baby kitten. the only way you can tell its balls. if it has some then its a boy.
