These are the three
major classes of
fingerprint patterns.
• Who is loops, arches
and whorls?
This is the most
common ridge pattern.
• What is a loop?
This is the number of
deltas found in a
typical arch pattern.
What is zero?
• What is a whorl?
•What is a double loop?
There are
approximately this
many ridge
characteristics in the
average fingerprint.
• What is 150?
• What is a ridge ending?
• What is a bifurcation?
• What is a dot?
•What is a lake?
A person’s fingerprints
are formed at this
time.
• What is during fetal
development?
This is the purpose of
friction skin ridges.
•What is to get a firmer
grip and resist slippage?
The pores of the sweat
gland are located in
this.
• What are the skin
ridges?
In order to permanently
damage the fingerprint,
one must damage this
layer of skin.
• What is the dermal
papillae?
Sweat glands on the
friction ridges do not
produce this molecule,
which is common in all
other sweat glands.
• What is oil?
The fingerprint
classification system
that classifies prints
based on the number
and location of whorls is
called this.
• What is the Henry system?
This is what determines
the minimum number of
ridge characteristics
needed to match two
fingerprints
• What is the experience of
the investigator?
The computerized
system for storing
fingerprints is known
as this.
• What is AFIS?
These are two of the
Daubert criteria that
fingerprint analysis
does not meet.
• What are it does not have any
standards and you cannot
determine its potential rate of
error?
This man had an
almost exact double
who had the same
Bertillion
measurements as him.
Who was Will West?
Prints that are not
readily visible are
known as this.
•What is latent?
Prints impressed into a
bar of soap are known
as this.
•What are plastic prints?
Sublimation occurs with
the use of this lifting
method.
•What is iodine fuming?
Ninhydrin is used to
detect this type
molecule in latent
fingerprints.
•What are amino acids?
Superglue fuming is not
suitable for this type of
surface.
•What is a porous surface?
This is an example of a
porous surface.
• What is paper, wood,
cloth, etc.?
This fingerprinting
method produces a
temporary orange/brown
print.
• What is iodine fuming?
This chemical
treatment produces a
white-appearing
permanent fingerprint
• What is Superglue fuming?
This fingerprinting method
produces a permanent
purplish print.
• What is ninhydrin?
These two fingerprinting
methods are used on
porous surfaces.
• What are iodine fuming
and ninhydrin?
