Objectives
To design and propose an innovative experiment (for class IX-XII) on distribution of patterns of fingerprint among classmates (A).
To find out distribution of patterns of fingerprint of school teachers in relation to gender & blood group (B).

It is an impression left by friction ridges of a finger
A friction ridge is a raised portion of the epidermis Fingerprint patterns are genetically determined
Every major event between week 6 and week 21 of fetal life leaves its mark on fingerprints
It has 3 types: loops, whorls & arches
Biology of fingerprint
![Page 5: Study on distribution of patterns of fingerprint](https://reader035.vdocument.in/reader035/viewer/2022081605/58edf5511a28ab50618b46bd/html5/thumbnails/5.jpg)
The worldwide percentage of loops, whorls, arches and composite
is 65%, 25%, 7% and 2-3% respectively (Nandy, 2001)
Distributions of fingerprint patterns are similar on both hands in
both sexes (Tanuj and Saurabh, 2006)
These fingerprint patterns correlate to the amount of hormones,
environmental factors and nutrients that we were exposed to in
utero and genes of developing body
Fingerprints are easily deposited on suitable surfaces by exocrine
glands

Part A
Designing and proposal of innovative experiment
I. Materials required:
Ink pad, white sheets, magnifying lens, scale, pencil and cleaning cloth.
II. Method /Procedure
1. On an A4 sheet draw 16 small boxes (4 row x4 column)
2. Give running number to each box
3. Collect the fingerprint (left thumb)
4. Write their name, gender and blood group in the box

5. Identify and note its’ pattern with the help of magnifying lens
6. Calculate percentage of patterns for male & female, A, B, AB & O, Rh+ve & Rh-ve and whole class
7. Observe the difference if any and (Chi-square & ‘t’ test)
8. Make an effort to explain why the difference?

III. Suggested ideas for extension of the study
fingerprint and lifestyle
smokers & non-smokers, alcohol takers & non-alcohol takers, singers & non-singers, veg & non-veg etc.
fingerprint and profession
different professionals like, doctors, nurses, engineers, teachers, drivers, police men, shop keepers etc.

Conclusions
loop is the dominant and mixed is the least pattern
There exists gender based difference in pattern
we sincerely believe and propose that this study as an innovative, effective and low-cost experiment for IX – XII classes
This view is acknowledged / accepted by most of the teachers of ACES and DMS, Mysore.
