The American Biology Teacher, a nationally recognized journal, offers articles on recent advances in biology and life science, instructional activities for the classroom and laboratory, and interdisciplinary programs. These singular points are useful for fingerprint indexing, i.e., for classification of fingerprint types [16], fingerprint alignment and orientation field modeling [17, 18] and identification or verification. This backward turn or loop is distinguished by how the loop flows on the hand and not by how the loop flows on the card where the imprint is taken. Forensic Science: Fundamentals & Investigations, Chapter 6 * Characteristics of Fingerprints There are 3 general fingerprint distinctions: ARCH WHORL LOOP About 5% About 30% About 65% of the population Arch An arch has friction ridges that enter on one side of the finger and cross to the other side while rising upward in the middle.
