London IDEAS Education Dr Gail Davies An Introduction to DNA & Forensics Looking at Simple DNA Profiles

Looking At DNA DNA patterns DNA Fingerprints

DNA Fingerprints are Difficult to Interpret

DNA Profiles: Look at Set Places in Our DNA Forensic Science Service 11 different places Lots of variation at those places Someone having the same profile as you: One in a thousand million 1 in 1,000,000,000

Uses Of DNA Profiles Family relationships –Who is the father? –Are they brothers? –Are twins identical? Identification –Crime Suspect/Victim –Disasters

Who is the Dad?
