Over the past twenty years or so I have written a number of books around the topic of DNA which you might like to read to give a fuller account of the science behind your DNA test. Though the books necessarily contain some technical details they are principally aimed at the general reader with no specialist knowledge. They are as far removed from textbooks as I could manage. I suggest you start with The Seven Daughters of Eve and take it from there.
