The circuit on the left is source degenerated so the effective gm will be gm/(1+gmR). And the gain will be gm effective *ro

You're wrong! The small signal voltage gain of that circuit is not equal to zero.

It is correct. Unless the model is different then the one showed. Pls grasp whats your model.

@@coolwinder No, is not. The gain factor on a Jfet is its transconductance and it is dependent of the current in the drain. The gain of the first excercise explained is Vout = Vin*gm*R ... all this assuming it is not connected to any load in witch case the final expression will be Vout = Vin*gm*(R//Rl). One more thing, you might see gm as Yfs. Same thing, different name.
