The Examiner noticed a pattern with two deltas and two separate loop formations. When a line is connected from the core to the delta, the recurving ridge is also touched. However, the all the looping ridges are abutted by an appendage. What is the pattern being indicated?

• Double loop whorl

• Tented arch

• Accidental whorl

• Plain whorl

The very first thing to do in fingerprint classification is

• to ink the ink slab

• to be sure that the rolled impressions are in proper place

• check if the hands of the subject are dry

• to be sure that the subject is not hungry

When a pattern shows a series of bifurcation opening towards the core at the point of divergence of the type line, the bifurcation _________ the core is chosen as the delta

• Outside

• Inside

• Nearest

• Farthest

In sub- secondary classification, this pattern is found on the right index. What is the classification of the said finger?

• Inner

• Outer

• Meeting

• Small

Renz is examining a loop pattern. It appears that the innermost recurving ridge has an appendage. Which among the following should be selected as the core?

• The shoulder farther from the delta of the innermost recurve can be selected as the delta

• The shoulder of the next outer recurving ridge having an appendage should be selected as the delta

• The shoulder of the next innermost recurving ridge without an appendage should be selected as the delta

• The shoulder of the next outer recurving ridge without an appendage should be selected as the delta

When used in developing fingerprints, it is typically applied to adhesive materials like paper tape and packaging tape. It's a dyeing method, where the powder adheres to the fingerprint residues on these surfaces. The powder is also used on other surfaces, including paper, wood, and metal, and can be applied by either dusting or soaking methods.

• Victoria pure blue

• Dusting method

• Cyanoacrylate

• Ninhydrin method

In the context of fingerprint terminology, what does the acronym ACE-V stand for?

• Acquisition, Verification Comparison, Expertise, and verification

• Analysis, Comparison, Evaluation, and Verification

• Analysis, Validation Correlation, Evaluation, and Validation

• Association, Comprehension, Examination, and Validity

Which of the following statements is incorrect?

• Monozygotic twins have almost identical DNA, with slight differences.

• Monozygotic twins possess identical fingerprints.

• Each individual has unique DNA.

• No two fingers can have the same fingerprints.

In ridge tracing, when the tracing ridge definitely ends the tracing ridge should____

• Continue to the one adjacent to it

• Immediately drop down the next ridge

• Go above the tracing ridge

• Immediately terminate and count the intervening ridges from there

Matthew noticed an accidental whorl pattern which has 3 deltas. When performing ridge tracing what deltas should be used?

• Used the innermost deltas

• Use the outermost deltas

• Only the left delta should be used

• Only the right delta should be used
