Your DNA determines how many muscle fibers a person is born with. This number never changes cause one can't make more muscle fibers during their lifetime. With more muscle fibers, one has the potential to be stronger.
It is an acquired trait because you could train your muscles to become bigger. When you train, for example resistance training, your muscle produces more myofilaments which increases their diameter. This is why you develop large muscles when you train.
