Question

1. ______ what type of pattern is displayed by this print?

a. plain arch
b. tented arch
c. radial loop
d. ulnar loop
e. plain whorl
f. central pocket whorl
g. double loop/whorl
h. accidental whorl

1. on the fingerprint, find and label each of the following:

• short ridge
• island ridge
• dot
• ridge - ending
• bifurcation
• eye or island
• delta

Explanation:

A plain whorl fingerprint pattern has circular or spiral ridges that make at least one complete circuit, with two deltas (though sometimes the second delta can be hard to see but the circular structure is key). The given fingerprint has a circular, whorl - like pattern consistent with a plain whorl. Arches (plain or tented) have no loops or whorls, loops (radial, ulnar) have one delta and a loop, and other whorl types (central pocket, double loop, accidental) have more distinct features not seen here. So the pattern is a plain whorl.

Answer:

e. Plain Whorl
