What are the basic steps of IGG?

• A. Collecting DNA samples, analyzing genetic data, building family trees, identifying potential relatives, and confirming identities.
• B. Verifying age, sex, and ancestry from skeletal remains only.
• C. Cataloging dental impressions and masticatory patterns.
• D. Generating a list of potential suspects based on location.

Answer: (A)

Integrated Genetic Genealogy combines DNA analysis with genealogical research to identify individuals. It starts with collecting DNA samples and ensuring proper chain-of-custody. The genetic data are then analyzed to determine relationships and identify potential relatives. Next, genealogical research is used to build family trees that connect these relatives across generations. By tracing shared DNA and lineage, investigators identify potential matches and narrow down who the person might be. Finally, identities are confirmed through corroborating evidence from records and other forensic information, converging on a single identification. This workflow aligns with collecting DNA, analyzing genetic data, building family trees, identifying potential relatives, and confirming identities. The other options describe methods outside this integrated genetic and genealogical approach.
