What are minutiae points in fingerprint analysis?

Back

Minutiae points are specific points where the ridge structure of a fingerprint pattern changes.

What is the most common method for lifting fingerprints?

Back

The most common method for lifting fingerprints involves dusting with black powder and lifting the print with clear tape.

What is the most common fingerprint pattern?

Back

Loops are the most common fingerprint pattern.

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 the significance of delta in fingerprint patterns?

Back

A delta is a point on a fingerprint pattern where two ridges diverge, and it is crucial for classifying fingerprint patterns.

Front

What is the role of friction ridges in fingerprints?

Back

Friction ridges are the raised portions of the skin that form the unique patterns of fingerprints, aiding in grip and tactile sensation.
