Are mutations pre-existing at low frequency within population?

    We all have a handful of mutations - most of them do nothing.

    Yes.

    1. You have about 100 mutations that you did not inherit from your parents. It's unlikely but possible that you are the only person on Earth with a particular mutation.

    2. Many mutations that confer antibiotic resistance in bacteria are mildly detrimental in wild populations. Although these are removed by natural selection they keep occurring so they always exist at low frequencies. (At least until that antibiotic starts getting used)

    this question makes no sense.

    Compared to our parents, we all have a few copying errors. Sometimes they get passed on and spread, sometimes they don't get very far.

    In that sense they all start out at the lowest possible frequency, but some of them spread to a majority of some generation(s)
