The lift and drag imbalance between the left and right ailerons creates adverse yaw. This creates more lift and drag on the upgoing wing (left) and less on the downgoing (right) wing. The differential lift and drag are the main causes of adverse yaw. Any increase in lift causes induced drag to increase as well.

The aileron on the right wing deflects down, increasing the camber and creating more lift. While the tilting lift vectors are an important source of adverse yaw, drag also plays a part. Any time a wing creates lift, it creates induced drag. This drag imbalance amplifies the adverse yaw. The lift imbalance causes the roll.

The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. The problem is that the aileron can only be deflected to a point after which the drag becomes significant.
