Three general fingerprint pattern types
Fingerprints patterns are of three types: arches, loops and whorls, and loops are the most common pattern, being found in 65 to 70 percent of all fingerprints in this pattern, ridges or curved lines enter from one side of the finger, form a loop and exit from the same side loops have one delta, a .

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). There are basically three main forms of patterns that are made by the ridges of fingerprints 1) loops: loops make up almost 70 percent of fingerprint patterns they originate from one side of the finger, curve around or upward, before exiting out the other side. The genes from our parents determine the general characteristics of the pattern sir francis galton was the first person to classify fingerprints into different types based on the three basic features: loops, arches, and whorls. A fingerprint pattern will remain unchanged for the life of an individual however, the print itself may change due to permanent scars and diseases fingerprints have general characteristic ridge patterns that allow them to be.
Fingerprint patterns appear on the end of each finger of each individual there are 3 basic pattern types which are the (1) arch (2) loop and (3) whorl these 3 pattern types are then sub-divided into a total of 8 types, which are:. Francis galton and fingerprints although galton was not the first to propose the use of fingerprints for identification (sir william herschel had used them in india for this purpose) he was the first to place their study on a scientific basis and so lay the groundwork for their use in criminal cases.

Population percentages of fingerprints patterns all other subcategories of fingerprint cryptococcal neoformans strains, china | cdc eid to determine the population structure of the cryptococcosis agents in china, we . Below are the three basic pattern types the loop is the most common fingerprint pattern all over the world to identify the three patterns, note the ‘delta’, the point where lines from three directions come together. All fingerprints are divided into three classes on the basis of their general pattern: loops, whorls, and arches sixty to sixty-five percent of the population has loops, thirty to thirty-five.
Any fingerprint pattern which contains 2 or more deltas will be a whorl pattern there are four types of whorl patterns plain whorls consist of one or more ridges which make or tend to make a complete circuit with two deltas, between which an imaginary line is drawn and at least one re-curving ridge within the inner pattern area is cut or touched.
