Besides which, the technique and form you use will effect how it works out those muscles as well. Personally, deadlifts don't really add a whole lot to my quads, but with deads I can add size to my glutes, calves and hams quite readily. Leg development would be lacking without squats.
Chins don't equate to overall back development for me. They tend to hit my lats and biceps but the rest of my back doesn't get much from them. I need bentover rows for the rest of the back.
And so on and so on.
