Analysts use the general pattern type (loop, whorl or arch) to makeinitial comparisons and include or exclude a known fingerprint from further analysis.

The patterns to which numerical values are assigned in deriving the "primary" in the extension of the Henry System of fingerprint classification used by the Federal Bureau of Investigation are the whorl-type patterns, which occur in about 30 percent of all fingerprints.

A chart illustrating fingerprint ridge patterns (arches, loops and whorls) and fingerprint ridge characteristics (core, ending ridge, short ridge, fork or bifurcation, delta, hook, eye, dot or island, crossover, bridge, enclosures, and speciality).

2015年1月21日 · - General patterns on the volar areas are determined by heredity and genetic master plan. - Friction ridges are randomly formed because of biological variation. - Biological variations are due to environmental influences occurring during fetal development.

Everyone's fingerprints are unique. However, specific patterns can be seen in fingerprints. The three main types of fingerprints are separated into multiple categories within each category. Also Read: What is Fingerprint?

Fingerprint Patterns - Whorl Tracings There are two components of a whorl classification. The first is the whorl pattern such a plain, double, central pocket, accidental and the second is the tracing. The tracing is relatively simple. Image #4 at left is a plain whorl pattern. To determine the tracing we

The fingerprint pattern, such as the print left when an inked finger is pressed onto paper, is that of the friction ridges on that particular finger. Friction ridge patterns are grouped into three distinct types—loops, whorls, and arches—each with unique variations, depending on the shape and relationship of the ridges:

Display detailed images and definitions of various fingerprint patterns on your walls for your students to study. The poster shows loops, arches, and whorls, as well as specific friction ridge characteristics such as bifurcation, enclosure, ridge endings, and more.

These are the commonly known types of fingerprint patterns that have been firmly established by fingerprint examiners and experts all over the world. They help in classifying the unique fingerprints of different people into types and sub-types, which …
