Mitochondrial DNA and its Role in Contemporary Paleoanthropology
... By contrast, mtDNA is passed on to an individual only from that person’s mother, and it is passed on with (virtually) no change. This point bears emphasizing: all of a person’s mitochondria are derived from his or her mother only – there is ordinarily no paternal contribution [4]. Because of this f ...
