Forensic Science Fingerprint and Impression

Any print can identify a criminal if it shows an adequate number of ridge (minutiae) characteristics

• False

• True

Answer explanation

True. A print can identify a criminal if it contains a sufficient number of ridge characteristics, known as minutiae, which are unique to individuals and can be used for accurate identification.

Tile is a porous surface

• False

• True

Answer explanation

Tile is typically made from materials like ceramic or porcelain, which are not porous. Therefore, the statement that tile is a porous surface is false.

Cardboard is a porous surface.

• False

• True

Answer explanation

Cardboard is indeed a porous surface, meaning it has tiny holes or spaces that allow air and moisture to pass through. This characteristic makes the statement true.

Cloth is a nonporous surface

• True

• False

Answer explanation

Cloth is not a nonporous surface; it is porous, allowing air and moisture to pass through. Therefore, the statement is false.

Identical twins have the same fingerprints

• True

• False

Answer explanation

Identical twins do not have the same fingerprints. While they share the same DNA, fingerprints are influenced by environmental factors in the womb, leading to unique patterns for each individual.

After lifting a fingerprint you should photograph them.

• True

• False

Answer explanation

True. Photographing lifted fingerprints is essential for documentation and analysis, ensuring that the evidence is preserved and can be reviewed later.

Dentology is the study of fingerprints

• True

• False

Answer explanation

Dentology is not the study of fingerprints; that field is called dactyloscopy. Therefore, the statement is false.

Dactyloscopy is the study of fingerprints

• True

• False

Answer explanation

Dactyloscopy is indeed the study of fingerprints, making the statement true. This field is crucial in forensic science for identifying individuals based on their unique fingerprint patterns.

Accidental is the most common ridge pattern

• False

• True

Answer explanation

The statement is false because the most common ridge pattern is the loop, not the accidental pattern. Accidental patterns are less frequently observed in fingerprints.

Arch is the most common ridge pattern

• True

• False

Answer explanation

The statement is false because the loop pattern is the most common ridge pattern in fingerprints, not the arch pattern. Arches are less common compared to whorls and loops.
