Having DNA samples of all or almost all members of a population of, say, a few hundred or thousand individuals, is it possible to draw the entire family tree of those individuals? (Let's not assume monogamy or any other facilitation).
This may be a sum of two different questions:
does comparison of two DNA samples give any information other than topographical distance between individuals? In other words, is it possible to tell two sisters from a mother and a daughter by DNA alone?
(more a mathematical question than a biological one, maybe) having the relative topographical distance of all members of a group, can their full graph be drawn?
