1. The average fingerprint has approximately how many individual ridge characteristics?
a) 300
b) 75
c) 225
- d) 150
2. It is currently concluded that the minimum number of friction ridge characteristics, which must be present in two impressions in order to establish a positive identification is:
a) 6
- b) there is no minimum number
c) 10
d) 8
3. Whorls are divided into how many different groups?
a) 5
b) 3
- c) 4
d) 2
4. The inner layer of skin, is known as the:
a) Epidermis
b) Friction ridge
c) Minutiae
- d) Dermis
5. What were James Earl Ray's fingerprints, NOT found on?

True False (1pt each)
Indicate whether the statements below are true or false. If false correct it to make the statement true.
6. It is assumed that no two people have the exact same fingerprint.
True
7. With the exception of any life experiences resulting in a scar or damage, a fingerprint will remain unchanged during an individual's lifetime.
True
8. The most common type of fingerprint pattern is the arch pattern.
False, because the most common fingerprint is the loop pattern.
9. AFIS makes it possible to compare a single print from a crime scene against an entire database of fingerprints.
True
10. A trained fingerprint examiner is not required once AFIS has made a match.
False, because a trained fingerprint examiner is always required to make a final choice.
11. There is currently an integrated footprint database.
False, because there is no footprint database.
Matching (2pts each)
Match the print with the best possible definition below.
