        Build a Family Tree

        Except for random mutations, a son inherits an exact copy of his father's Y chromosome, which he inherited from his father. In this interactive feature from the NOVA: Lost Tribes of Israel Web site, your task it to complete a family tree by comparing the DNA sequences of Y chromosomes of known men to the sequences of their relatives.

        This resource can be found on the NOVA: Lost Tribes of Israel Web site.
