How does DNA evidence from skeletal remains contribute to a presumptive identification?

• A. Relies solely on mtDNA without anthropological context
• B. Combines mtDNA or nuclear DNA typing with anthropological context and reference family/maternal lineages to identify remains
• C. Uses only dental records
• D. Does not require any anthropological information

Answer: (B)

DNA evidence from skeletal remains contributes to presumptive identification by providing a genetic signal that is interpreted in the light of physical characteristics and known family relationships. Using mtDNA can be especially valuable when the remains are old or degraded, because mtDNA is present in many copies per cell and traces maternal lineage, helping narrow the pool to individuals who share that maternal line. Nuclear DNA offers more granular discrimination when quality permits, enabling kinship analyses that can link the remains to specific relatives through STR or SNP profiles. But DNA results don’t stand alone. The anthropological context—estimates of ancestry, sex, age at death, and stature—shapes which individuals are likely matches and helps interpret partial or degraded genetic data. Reference family material, including maternal-line relatives for mtDNA and appropriate kin for nuclear DNA, provides the comparison samples needed to assess kinship and move toward an identification. When the genetic data align with the anthropological assessment and a plausible set of relatives, you reach a strong presumptive identification. Relying on DNA alone or ignoring context and reference lineages would limit interpretation and could lead to misidentification.
