What percentage of all fingerprint patterns are classified as whorls?

The classification of fingerprint patterns is based on a commonly accepted distribution among the three main categories: loops, whorls, and arches. Whorls make up about 30-35% of all fingerprint patterns. This statistical information indicates that a significant portion of the population exhibits this pattern type, reflecting its distinct characteristics, such as having two or more deltas and a circular or spiral arrangement of ridge lines.

Choosing the answer of 35% aligns closely with current forensic and fingerprint analysis training, as it accurately captures the approximate average percentage of whorls among the population. Being familiar with these statistics is essential for forensic analysts, as it helps in understanding how to classify and analyze fingerprint evidence during investigations and when using database systems.
