Only if someone was asllep at the switch on the assembly line!
The gear ratios are the same that way all four wheels turn at the same speed. A 4x4 has two differentials, an AWD has three. Each axle has a diff, this allows one wheel to turn at a different speed to the other wheel on that axle. In the simplest form only one wheel is powered, the other wheel is along for the ride. Tends to be the wheel with less traction gets the power hence why a 5 litre Mustang just sits and spins and goes backwards down a snowy hill that he's trying to get up. So in the 4x4 Ram we split that power front and back through the transfer case that way we're powering one wheel in the front and one wheel in the back. In an AWD their transfer case is basically a differential cending power either to the back axle or front. AWD do use an certain amount of hocus pocus to devide the power otherwise you'd just have a higher, boxier Mustang spining one wheel either in the front or back. 4x4 guys can further power all their wheels at the same time by using locking differentials, so that both wheels on the same axle are locked together like the transfer case does for the front and back.
Now the reason for your symptons on tight turns is because all four wheels are following a different circle, therefore all 4 wheels need to turn at different speeds. Going forwards 4x4's are fine because all four wheels are travelling the same distance at the same speed, sloppy or dry it's fine just uses more gas because the engine is working harder to power the front diff. In tight turns, with two power wheel locked to gether something has to give. Sloppy conditions like snow or wet mud allow the front wheel to slip therfore letting it speed up to match the speed of the rear wheel. On dry pavement it doesn't slip (at least not easily) and that's what you're feeling, pushing the front tire to the point of maximum traction, letting it lose traction only to find traction again, then only to lose traction. Very hard on the tires, very hard on the drivetrain. So yes slip it back into rwd on tight turn on dry pavement.
