Fingerprint Pattern
Variations pattern of ridges found on the fingers, palms and soles that has a complex genetic basis. These skin ridges develop in humans between 11th and 17th week of gestation and are mainly used for better gripping. Ridge patterns appear to be at least partially determined by genetic factors, but there are also important effects caused by developmental processes. The details of the genetic basis for dermatoglyphic variability in human populations are poorly understood and are likely to be highly complex. Everyone's prints are unique, Fingertip patterns have been generally categorized into three basic patterns: arches, loops and whorls.
