Yes, and usually our best "balancing" leg is the opposite from our dominant arm, while out best "power" leg is the same as our dominant arm. Try balancing on one leg and kicking with the other and you'll see the preference.
I don't see how that applies to having more fat on one leg than the other, though.
Humans are very non-symmetrical. If you take a picture of your face and divide it down the center, then make one copy reversed and put the two "left" sides together and the two "right" sides together, it will look like two different people ("sisters," but not identical. One usually looks older. According to some facial analysis system, you inherit the right side of your face from your mother, and the left side from your father).
