There are several variants of the Henry system, but that used by the Federal Bureau of Investigation (FBI) in the United States recognizes eight different types of patterns: radial loop, ulnar loop, double loop, central pocket loop, plain arch, tented arch, plain whorl, and accidental.
Beside above, what is the rarest fingerprint pattern? Arch
Beside above, how many types of fingerprint patterns are there?
Three basic patterns of fingerprints exist, within them there are, depending on the source, potentially dozens of subclassification. The basic 3: Loop, Arch, Whorl. So arches are most rare. Interestingly enough, apes have only whorls, and people with downs syndrome tend to have all arches.
Which fingerprint pattern is the most common?
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.
