In a front wheel drive vehicle, since the tranny has to be positioned to turn the front wheels, it's placed off the center of the vehicle and turned. Hence, the distance from the differential to each of the front tires is different so torque steer occurs. This only happens when you floor it on a high powered car... not giving enough time for the differential to negotiate the power.
In a rear wheel drive vehicle, the drive shaft usually runs down the center of the car... and so the differential is located in the center (with respect to width). The distance between each rear wheel to the differential is the same... therefore, no torque steer.
