Flee at Once ! All is Discovered !
12th June 2021
In the last few years, law enforcement has begun to cash in on modern genetic technology in a new and more powerful way, one that works on perps that have been careful enough to avoid being genotyped.
The perp’s DNA sample is matched against a large database of genome sequences, and if a moderately long subsequence is identical-by-descent, it’s clear that the perp and the matching person in the database share fairly recent common ancestry. The degree of sharing shows, approximately, how recent that common ancestry is.
It doesn’t matter whether you’ve gotten your genes sequenced — if any of your relatives have, you’re under the spotlight.
