Fingerprint and Tattoos MCQs

Ans. is 'b' i.e., Tooth [Ref Parikh 6th le p. 7.2-7.15] DNA finger-printing/ DNA profiling Is a technique employed by forensic scientists to assist in the identification of individuals by their respective DNA profile it is a fool proof method to conclusively fix the paternity/ maternity. The most desirable method of collecting a reference sample is the use of a buccal swab. When this is not available (e.g. because a court order may be needed and not obtainable) other methods may need to be used to collect a sample of blood, saliva, semen, or other appropriate fluid or tissue from personal items (e.g. toothbrush, razor, etc.) or from stored samples (e.g. banked sperm or biopsy tissue)

Explanation: DNA profiling is a highly reliable method for identifying a body, even when it is in an advanced state of decomposition. Explanation for other options: General Recognition (Option A): Not reliable due to significant alteration of features from decomposition. Dental Records (Option C): May not be available for a vegetable vendor, making this method less practical. Fingerprints (Option D): More dependable if the deceased has a criminal record; otherwise, fingerprints may not be useful.

Quetelet's rule: Every nature-made object shows infinite variations of forms, and in the world’s, crime records no two identical fingerprint patterns have been reported. Hence, it is unique to every individual. Fingerprint pattern differs even in identical twins. Blood group, DNA fingerprinting and iris color are same in identical twins Reference: Textbook of Forensic Medicine & Toxicology, Anil Aggrawal, Page No. 104

Black areas in a tattoo are the least likely to fade over years. This is because the black pigment (carbon particles) are more resistant than the other pigments to transportation by the lymphatic system. Thus, they tend to persist in the skin. Colors such as blue, green, or red are scavenged by tissue cells and leached into the lymphatic system after a number of years or decades. Light colors such as white, pink, and blue fade faster.

The first ever Finger Print Bureau in the world was established at Writer's Building at Calcutta (now Kolkata) in the year 1897. Reference: https://ncrb.gov.in/en/central-finger-print-bureau

All fingers can be used for fingerprinting system Fingerprint reader [FINDER] is a computerised automatic finger print reading system which can record each fingerprint data in half second. Prints of eight fingers are recorded excluding little fingers. Reference: The Essentials of Forensic Medicine & Toxicology, KS Narayan Reddy, 35th edition, Page No. 63

Identical twins have the same DNA fingerprint pattern, HLA system and Blood group. But the fingerprints pattern is different in identical twins, that's why it's the best method of identification.

Ink blotting is not used to visualize tattoos. A faded tattoo mark can be visualized by: Ultraviolet light Infrared photography Rubbing the part and examining it with a magnifying lens Reference: The Essentials of Forensic Medicine & Toxicology, KS Narayan Reddy, 35th edition, Page No. 67, 68
