1. Which principle states that no two individuals have identical
fingerprints, forming the foundation of forensic fingerprint analysis?
A. Principle of Individuality
B. Principle of Persistence
C. Principle of Classification
D. Principle of Reconstruction
Answer: A
Rationale: The principle of individuality asserts that fingerprints are
unique to each individual, even among identical twins, making them
reliable for identification purposes.
,2. Which type of fingerprint pattern is characterized by ridges entering
from one side, rising in the center, and exiting on the same side?
A. Loop
B. Whorl
C. Arch
D. Composite
Answer: A
Rationale: Loop patterns involve ridges entering and exiting from the
same side, forming a curved structure with one delta.
3. What is the minimum number of deltas found in a typical whorl
fingerprint pattern?
A. Zero
B. One
C. Two
D. Three
Answer: C
Rationale: Whorl patterns are defined by the presence of at least two
deltas, distinguishing them from loops and arches.
4. Which fingerprint pattern lacks any deltas and core structures?
A. Loop
B. Whorl
C. Plain arch
D. Central pocket loop
, Answer: C
Rationale: Plain arches are the simplest fingerprint patterns and do
not contain deltas or cores.
5. What is the term for the central point of a fingerprint pattern?
A. Delta
B. Core
C. Ridge ending
D. Bifurcation
Answer: B
Rationale: The core is the approximate center of the fingerprint
pattern and is used for classification and comparison.
6. Which term describes a ridge that divides into two separate ridges?
A. Ridge ending
B. Island
C. Bifurcation
D. Dot
Answer: C
Rationale: A bifurcation is a ridge characteristic where one ridge
splits into two branches, commonly used in fingerprint comparison.
7. What is the primary purpose of AFIS (Automated Fingerprint
Identification System)?
A. To collect fingerprints at crime scenes
B. To store and compare fingerprint data
, C. To enhance fingerprint visibility
D. To classify fingerprints manually
Answer: B
Rationale: AFIS is designed to store large fingerprint databases and
perform automated comparisons for identification.
8. Which method involves applying powder to reveal latent fingerprints?
A. Chemical processing
B. Physical development
C. Dusting
D. Fuming
Answer: C
Rationale: Dusting uses fine powders that adhere to oils and residues
in latent prints, making them visible.
9. What type of surface is most suitable for powder dusting techniques?
A. Porous surfaces
B. Rough surfaces
C. Non-porous smooth surfaces
D. Wet surfaces
Answer: C
Rationale: Smooth, non-porous surfaces such as glass or metal allow
powders to adhere effectively to latent prints.
10. Which chemical is commonly used to develop latent fingerprints
on porous materials like paper?
