Are Fingerprint Patterns Inherited
As one of the many fields of forensic science that can benefit from additional research, fingerprint identification is probably the most deserving. Within recent years, many print examiners have been questioned in both professional and social situations as to whether fingerprint evidence should be considered scientific. This questioning caused latent print examiners to realize the pressing need for various types of ongoing research on the subject of fingerprints.
Fingerprint patterns are formed on the fetus in the womb. Wertheim and Maceo reported that various cellular attachments ensure the prominence of friction ridges, while cellular stresses and cellular distributions account for all "three levels"

Fingerprints have a general flow to the ridges that translates into one of three major pattern types: a whorl, loop or arch. It is possible to have just one, two or all three-pattern types among your 10 fingerprints. The important thing to remember about pattern types is that an individual cannot be identified from fingerprints by pattern type alone. To make identification, an examiner must look to the next level of detail: the specific path of ridges and the breaks or forks in the ridges, known as minutiae. Other identifying features such as creases, incipient ridges (nascent ridges found in the furrows) and the shapes of the ridge edges are also useful for identification purposes.
Early pioneers in the field of dermatoglyphics (the study of FRS patterns) demonstrated a strong correlation between the inheritance of fingerprint pattern and the overall size, shape and spacing of the ridges. The identifying ridge features, however, are not inheritable, which is what makes every fingerprint unique.
Why are patterns inherited, but not the identifying ridge features? The reason lies in the timing of fetal development: two critical events in the formation of FRS collide during weeks 10 through 15. Fetuses develop smooth volar pads--raised pads on the fingers, palms and feet--because of swelling mesenchyme tissue, which is a precursor of blood vessels and connective tissues. Around week 10, the volar
