Paternal leakage is a rare exception to the strictly maternal inheritance of mtDNA. Mitochondrial DNA is a useful marker in phylogenetic studies and molecular systematics because of its maternal inheritance, haploid nature, and rapid rate of evolution (38). Finally, the maternal inheritance of mtDNA can prove advantageous in cases involving missing persons, even though this fact also makes it less discriminating than nuclear DNA because any person who is a member of the same maternal lineage will have the same mtDNA sequence. |
