They cannot distinguish between your maternal or paternal line that I know of. Time frame is also difficult to establish, but usually reckoned to be beyond the times that records began, that is thousands rather than hundreds of years.
Each of us had 50% autosomal DNA from our mother and 50% from our father, so by definition the 58%, if it is accurate, has to be from both parents, but in no fixed proportion.
