Question

On the end joints of the fingers, a number of basic patterns are formed by the friction ridge skin and remain constant:
A. Since its formation during embryonic life
B. Till delivery of the child
C. Through out the life of an individual after birth
D. Only till 6 months of gestation

• A. A and B only
• B. B and C only
• C. A and C only
• D. C and D only

Hint:

The core principles of fingerprints are that they are \textbf{unique} to each individual and \textbf{permanent} throughout life. They form before birth and last until after death.

Answer 1

The Correct Option is C

This question concerns the two fundamental principles of fingerprints: permanence and individuality.
Step 1: Analyze the principle of permanence. Friction ridge patterns are formed during fetal (embryonic) development and remain unchanged throughout an individual's entire life, barring deep scarring or decomposition after death.

Step 2: Evaluate the statements.
A. Since its formation during embryonic life: Correct. Fingerprints form deep in the dermis layer during the fetal stage.
B. Till delivery of the child: Incorrect. They persist long after birth.
C. Through out the life of an individual after birth: Correct. They remain constant from birth until death.
D. Only till 6 months of gestation: Incorrect. They are formed during gestation but persist for life.
Conclusion: Statements A and C together describe the principle of permanence. The patterns are formed in the womb and last for the entire life of the person.
