Biogeographical Ancestry
Although controversial, a few laboratories are now predicting a person's biogeographical ancestry based on SNP markers that have been highly correlated with certain geographic regions.
For example, a crime scene sample showing genetic markers that have been specifically associated with individuals from a certain part of the world may suggest to crime investigators that a suspect may have features associated with that region.
