1. Are Fingerprint Patterns Inherited Genetically?
By Melody Nordberg

2. Recognizing the Fingerprints seen in This Study
Only four of eight categories were seen on the right thumbs of participants

3. Plain Arch – Gentle, mound-like rise

4. Ulnar loop – Loop Entering from the Right

5. Plain Whorl – Circular Pattern

6. Double loop whorl – “S” shaped

7. Note: Images become easier to see when they are blown up

26. Results

27. The Patterns Seen in Participants:

28. 70% of Sibling Pairs Matched!

29. Only 33% matched when randomly paired!

30. Fingerprint Patterns are inherited Genetically!
