Unit 2: Fingerprint Analysis

Front

What is a Double Loop fingerprint?

Back

A Double Loop fingerprint is a type of fingerprint pattern characterized by two loops that swirl around each other, often resembling a figure-eight.

Front

What is the Enclosure/Eye minutiae in fingerprint analysis?

Back

The Enclosure, also known as the Eye, is a type of minutiae where a ridge bifurcates and forms a small enclosed space, resembling an eye.

Front

What is Magnetic Powder used for in fingerprint analysis?

Back

Magnetic Powder is a fingerprinting technique that uses a magnetic wand to apply powder to surfaces, making it less abrasive and more effective on delicate surfaces.

Front

When are fingerprints formed?

Back

Fingerprints are formed during fetal development, specifically around the 10th week of gestation.

Front

What is Fluorescent Powder used for?

Back

Fluorescent Powder is a fingerprinting technique particularly useful for revealing prints on multi-colored, busy, or dark surfaces due to its ability to fluoresce under UV light.

Front

What are the main types of fingerprint patterns?

Back

The main types of fingerprint patterns are loops, whorls, and arches.

Front

What is the purpose of fingerprint analysis?

Back

The purpose of fingerprint analysis is to identify individuals based on the unique patterns and minutiae present in their fingerprints.

Front

What is a Bifurcation in fingerprint analysis?

Back

A Bifurcation is a type of minutiae where a single ridge splits into two separate ridges.

Front

What is the significance of ridge count in fingerprint analysis?

Back

Ridge count is the number of ridges between two core points in a fingerprint pattern, used to help classify and identify fingerprints.

Front

What is the role of Ninhydrin in fingerprint analysis?

Back

Ninhydrin is a chemical used to develop latent fingerprints on porous surfaces by reacting with amino acids in sweat to produce a colored compound.
