This article will briefly survey some of the current and emerging legal issues surrounding mtDNA evidence. Parts I and II discuss basic evidentiary questions, including mtDNA's reliability and admissibility under Daubert as well as the potential problem of jury confusion regarding the probative value of mtDNA. Part III considers the broader potential of mtDNA to supplant microscopic hair analysis, a technique often criticized for its subjectivity and high error rate. Finally, Part IV explores the unique privacy concerns raised by the maternal inheritance of mtDNA, specifically in the context of DNA databanks.
