Like others, ridge counting values of the right hand are placed in the numerator and left hand in the denominator. The fingerprints are the friction ridges that are developed on the palm side of thumb and fingers. The number, relative location and identity of the characteristics impart individuality to a fingerprint. This article is made possible because of the efforts of Anuwanshi Sharma. Necessary cookies are absolutely essential for the website to function properly. Loops A loop is that type of fingerprint pattern in which one or more of the ridges enter on either side of the impression, recurve, touch or pass an imaginary line drawn from the delta to the core, and terminate or tend to terminate on or toward the same side of the impression from whence such ridge or ridges entered. Ridge parameters such as fingerprint ridge count, ridge density, ridge thickness to valley thickness ratio, ridge width and fingerprint pattern types are used for gender determination.
