The Federal Bureau of Investigation (FBI) recognizes eight different types of fingerprint patterns: radial loop, ulnar loop, double loop, central pocket loop, plain arch, tented arch, plain whorl, and accidental.
All fingerprints can be classified into three basic patterns: loops, whorls, and arches.
Although every fingerprint is different, they're all variations on three broad categories: the arch, which looks a bit like a cross-section of a hill; the loop, which is teardrop-shaped; and the whorl, which is reminiscent of a whirlpool.
There are four groups of whorls: plain (concentric circles), central pocket loop (a loop with a whorl at the end), double loop (two loops that create an S-like pattern) and accidental loop (irregular shaped). Whorls make up about 35 percent of pattern types.
Loop. The loop is the most common type of fingerprint. The ridges form elongated loops. Some people have double loop fingerprints, where the ridges make a curvy S shape.
But having such similarities to the naked eye doesn't mean the fingerprint composition is exactly the same. In fact, the National Forensic Science Technology Center states that, “no two people have ever been found to have the same fingerprints — including identical twins.”
Plain Arch – Raised ridges characterize this pattern and they extend from one side of the finger to the other in a continuous fashion. This pattern makes up a mere 5% of the total population, making it the rarest type.

Sgt. H. M. Smith, of the Bureau of Identification, Tacoma, Washington, then offered an amendment that the fingerprint be one of Sir Francis Galton's (often referred to as the "Father of Fingerprints").
As you age, skin on your fingertips becomes less elastic and the ridges get thicker. This doesn't change your fingerprint, but it's harder to scan or take a print from it.
They come from the same fertilized egg and share the same genetic blueprint. To a standard DNA test, they are indistinguishable. But any forensics expert will tell you that there is at least one surefire way to tell them apart: identical twins do not have matching fingerprints.
dactyloscopy, the science of fingerprint identification.
Dermatoglyphics [that is, palm and fingerprint patterns] provide a tool of unique value for human geneticists and physical anthropologists.
There are three main fingerprint patterns, called arches, loops and whorls. The shape, size, number and arrangement of minor details in these patterns make each fingerprint unique.
Fingerprints are classified into five categories: arch, tented arch, left loop, right loop and whorl. The algorithm extracts singular points (cores and deltas) in a fingerprint image and performs classification based on the number and locations of the detected singular points.
Fingerprints are classified in a three-way process: by the shapes and contours of individual patterns, by noting the finger positions of the pattern types, and by relative size, determined by counting the ridges in loops and by tracing the ridges in whorls.
Q: How long will fingerprints last? A: There is no scientific way to know how long a latent fingerprint will last. Fingerprints have been developed on surfaces that had not been touched in over forty years; yet not developed on a surface that was handled very recently.
Brandenburg's identification of Roscoe Pitts as Robert Philipps. Once identified, the police in Austin sent Philipps back to North Carolina where he was tried and convicted of the warehouse burglary. Although he had been caught and eventually identified, Philipps had successfully had his fingerprints removed.
Like many other complex traits, studies suggest that both genetic and environmental factors play a role. A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. These ridges are also present on the toes, the palms of the hands, and the soles of the feet.
Fingerprint Mechanics 1977) Delta - The delta is that point on a ridge at or in front of and nearest the center of the divergence of the type lines. The Core as the name implies, is the approximate center of the finger impression. Points of Identification - Ridge ending, bifurcation, enclosure, short ridge & ridge dot.
In short, your fingerprints reveal your neuromuscular potential and the genetic conditions that make you prone to stand out in certain physical activity.
But people with a rare disease known as adermatoglyphia do not have fingerprints from birth. Affecting only four known extended families worldwide, the condition is also called immigration-delay disease, since a lack of fingerprints makes it difficult for people to cross international borders.
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.
Adermatoglyphia is an extremely rare genetic disorder that prevents the development of fingerprints. Five extended families worldwide are known to be affected by this condition.
