Fingerprints

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 delta in fingerprint analysis?

Back

A delta is a point on a fingerprint pattern where two ridges diverge, typically found in whorl and loop patterns.

Front

How can you identify a loop fingerprint pattern?

Back

A loop fingerprint pattern is identified by ridges that enter from one side, curve around, and exit from the same side.

Front

What distinguishes a whorl fingerprint pattern?

Back

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

Front

What is the significance of minutiae in fingerprint analysis?

Back

Minutiae are the unique features of a fingerprint, such as ridge endings and bifurcations, used for identification.

Front

What is the difference between an arch and a loop fingerprint pattern?

Back

An arch pattern has ridges that rise in the center and flow outwards, while a loop pattern has ridges that enter and exit from the same side.

Front

What are the two types of loops in fingerprint patterns?

Back

The two types of loops are ulnar loops (flowing towards the little finger) and radial loops (flowing towards the thumb).

Front

How do you classify a fingerprint with no core or delta?

Back

A fingerprint with no core or delta is typically classified as an arch.

Front

What is the purpose of fingerprint analysis in forensic science?

Back

Fingerprint analysis is used in forensic science for identification and verification of individuals in criminal investigations.

Front

What is the role of ridge count in fingerprint identification?

Back

Ridge count is used to help differentiate between fingerprint patterns and can assist in identifying specific types of loops and whorls.
