ARE FINGERPRINT PATTERNS INHERITED GENETICALLY? By Melody Nordberg

RECOGNIZING THE FINGERPRINTS SEEN IN THIS STUDY Only four of eight categories were seen on the right thumbs of participants

PLAIN ARCH – GENTLE, MOUND-LIKE RISE

ULNAR LOOP –LOOP ENTERING FROM THE RIGHT

PLAIN WHORL – CIRCULAR PATTERN

DOUBLE LOOP WHORL – S “ ” SHAPED

NOTE: IMAGES BECOME EASIER TO SEE WHEN THEY ARE BLOWN UP. SOME CLASSIFICATIONS IN THE SLIDESHOW MAY NOT BE OBVIOUS AT THE CURRENTMAGNITUDE Ulnar Loop

RESULTS

THE PATTERNS SEEN IN PARTICIPANTS:

70% OFSIBLING PAIRS MATCHED!

ONLY 33% MATCHED WHEN RANDOMLY PAIRED!

FINGERPRINT PATTERNS ARE INHERITED GENETICALLY!
