Perhaps in the beginning when Hagoromo gave parts of his chakra to others, every person have same abilities, but some of them used one type of power than other ones and the other people used other type more Considering that by necessity, people with chakra would have to interbreed with non-chakra people, i think that alone could account for genetic drift.
