1. Gel Electrophoresis & DNA Fingerprinting
Essential Question: How is DNA fingerprinting used to establish genetic relatedness?

2. DNA Fingerprinting
DNA fingerprinting technique is used to identify individuals.
Also called DNA profiling.
Gel Electrophoresis is the name of the process used to develop a DNA fingerprint

4. DNA Fingerprinting
These gels are called "DNA fingerprints" because they are unique to every person--except identical twins
Parents and offspring have similar DNA profiles but not completely the same.
Blood relatives will have a higher degree of similarity of DNA profiles than any random individuals.

5. DNA Fingerprinting Practical Applications: Paternity Testing
Children get half of their DNA from their mothers & half of their DNA from their fathers.

6. Is Male 1 or Male 2 the father of this child?

7. Which “Dad” is the father?

8. DNA Fingerprinting Practical Applications : Forensics (crime analysis)
Profiles can be prepared from small amounts of blood, semen, hair, or skin cells
Suspect whose profile matches the evidence is most likely the culprit

9. Which suspect committed the crime?
