What is a fingerprint?

Back

A fingerprint is an impression or mark made by the pattern of ridges and valleys on the skin of a person's finger, unique to each individual.

Front

What are the three main types of fingerprint patterns?

Back

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

Front

What is a loop fingerprint?

Back

A loop fingerprint is a pattern where the ridges enter from one side, loop around, and exit from the same side.

Front

What is a whorl fingerprint?

Back

A whorl fingerprint is a pattern characterized by circular or spiral ridges that form a complete circuit.

Front

What is an arch fingerprint?

Back

An arch fingerprint is a pattern where the ridges rise in the center, creating a wave-like appearance.

What is the difference between a radial loop and an ulnar loop?

Back

A radial loop opens towards the thumb (radial), while an ulnar loop opens towards the little finger (ulnar).

How can fingerprints be used in criminal investigations?

Back

Fingerprints can be used to identify suspects, link them to crime scenes, and exclude innocent individuals.

Front

What is the significance of the uniqueness of fingerprints?

Back

The uniqueness of fingerprints means that no two individuals have the same fingerprint patterns, making them reliable for identification.

Front

What is the process of fingerprint analysis?

Back

Fingerprint analysis involves comparing the ridge patterns, minutiae points, and overall characteristics of fingerprints.

Front

What are minutiae points in fingerprint analysis?

Back

Minutiae points are specific features in a fingerprint, such as ridge endings and bifurcations, used for comparison.
