Which Fingerprint is Most Common?

Science project that asks "What is the most common fingerprints on humans" done by a student at TSBVI.

This science project was done by Alicia, who is a student at Texas School for the Blind and Visually Impaired (TSBVI).

Alicia is very interested in forensics and wanted to complete a science project related to forensics. 

Question

What is the most common fingerprints on humans?

  1. Describe the problem.  What is the most common fingerprint in humans?
  2. Gather information.  (Research) There are three types of fingerprints The three types of fingerprints are Whirls, loops, and ridges.  We found that the most common one was the loops with sixty to sixty five percent.  We also found out that whirls is the next common fingerprint with thirty to thirty five percent.  The least common would be arches or ridges with five percent.
