New view of what causes greatest genetic variability among individuals

A study by Yale researchers offers a new view of what causes the greatest genetic variability among individuals - suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged, or present in extra copies.
