Question 1

What is a 'bifurcation' in fingerprint ridge analysis?

Accepted Answer

A point where a single ridge divides into two ridges

Answer

A bifurcation is a minutiae type where one ridge splits into two separate ridges, forming a fork-like feature used in fingerprint comparison.

Question 2

What is a 'ridge ending' in fingerprint examination?

Accepted Answer

The point where a friction ridge terminates

Answer

A ridge ending is the point at which a friction ridge terminates — it is one of the most common Level 2 minutiae used in fingerprint comparison.

Question 3

What is meant by 'distortion' in a fingerprint?

Accepted Answer

Deformation in ridge appearance caused by pressure, movement, or surface irregularities during deposition

Answer

Distortion refers to the deformation of ridge detail caused by factors such as uneven pressure, lateral movement, or an irregular substrate surface during the deposition of the print.

Question 4

What does the term 'substrate' refer to in fingerprint examination?

Accepted Answer

The surface on which a fingerprint is deposited

Answer

The substrate is the surface or material on which a fingerprint has been deposited; its texture, porosity, and composition affect print quality and the development method selected.

Question 5

Which of the following best describes a 'partial print' in fingerprint examination?

Accepted Answer

A print in which only a portion of the friction ridge area is available for examination

Answer

A partial print is one that captures only part of the friction ridge skin, limiting the area available for comparison but not necessarily preventing individualization.
