Where do ridge patterns of fingerprints grow?
Epidermal layer
Dermal layer
Basal layer
Surface layer
Which of the following can alter fingerprint ridge patterns?
Washing hands frequently
Exposure to sunlight
Scars with damage to the dermal layer
Wearing gloves
Which of those below explain why scars that damage the basal layer may alter fingerprint patterns, while superficial injuries do not.
Because the basal layer is where ridge patterns are formed, so damage here can change the pattern permanently.
Because superficial injuries heal quickly and do not affect the underlying ridge patterns.
Because the epidermal layer regenerates fingerprints, but the basal layer does not.

Which of the following is NOT one of the basic ridge patterns found in fingerprints?

65%
50%
What is the ridge count in fingerprint analysis?
The number of loops in a fingerprint

Furrows
Which system currently evaluates over 20 minutiae patterns in fingerprints?
IAFIS (Integrated Automated Fingerprint Identification System)

Is there a standard number of minutiae patterns used for fingerprint identification?
No, there is no standard
Yes, 10 patterns
Yes, 54 patterns
Yes, 20 patterns
Why might the lack of a standard number of minutiae patterns be significant for fingerprint identification systems?
It can lead to inconsistencies in identification results.
It makes fingerprints invisible.
It increases the speed of identification.
It eliminates the need for computers.
What is the other name for "lakes" in fingerprint patterns?
Small enclosure
Small fragment
Double convergence
Bridge
What is the term for the point where a single ridge splits into two ridges in a fingerprint?
Dot
Bifurcation
Lake
Hook (spur)
Why are minutiae patterns important in forensic science?
They help identify the age of a person
The match provides individual evidence
They determine the color of fingerprints
They show how fingerprints are formed

US, Germany, Australia
France, Italy, Spain

The color of the print
The quality of prints and if it is a partial or full print
The age of the person
The type of ink used
