About this mock
This mock tests mastery of forensic hair examination at the hard level, covering scale patterns (imbricate, coronal, spinous), medullary index calculation and species thresholds, root phase identification (anagen, catagen, telogen) and the DNA recovery consequences of each, race determination from cross-section and pigmentation descriptors (Caucasoid, Mongoloid, Negroid), body area classification (scalp, pubic, beard, axillary, eyebrow), animal hair identification (dog, cat, rodent), mitochondrial DNA limitations and target regions (HV1, HV2), and the standards framework of ASTM E2227, SWGMAT guidelines, and the FBI/DOJ 2015 microscopic hair review.
Questions are calibrated to the UGC-NET Forensic Science Paper II Unit VII syllabus. In India, the Central Forensic Science Laboratory (CFSL) Kolkata trace evidence section handles hair comparison casework under standard protocols aligned with ASTM E2227 and SWGMAT, while CDFD Hyderabad provides mtDNA profiling from crime scene hair when nuclear DNA is unavailable. The FBI/DOJ 2015 review identified systematic overstatement of hair comparison significance in thousands of cases and remains a landmark reference for understanding the evidential limits of microscopic hair analysis worldwide.
Topics covered:
- Imbricate (human), coronal (rodent), and spinous (cat) scale patterns
- Medullary index: definition, calculation, and species thresholds (less than 0.33 human, greater than 0.50 animal)
- Anagen (bulb with intact sheath), catagen (partial sheath), and telogen (club root, no sheath) root phases
- Race determination: Caucasoid oval fine pigment, Mongoloid round dense pigment, Negroid flat coarse pigment
- Body area ID: scalp, pubic, beard, axillary, eyebrow and eyelash morphology
- Animal hair: dog (multiserial medulla), cat (spinous), rodent (coronal) microscopic features
- mtDNA limitations: maternal lineage only, HV1 and HV2 target regions, CDFD Hyderabad context
- ASTM E2227, SWGMAT guidelines, and the FBI/DOJ 2015 microscopic hair review
Ideal for MSc Forensic Science students, UGC-NET aspirants, and NFSU entrance exam candidates preparing for trace evidence and hair examination sections. Allow 30 minutes.
