All over our bodies, our skin is covered with glands and pores  including on the fingers. These glands give off sweat, which covers the surfaces of the fingers if there is enough of it, If we touch something with our hand, we leave behind a print of sweat. It has been determined that each one of us has a completely unique pattern of ridges on our fingertips, and that this pattern doesn’t change over the course of our lives. Even twins have different fingerprints. For this reason, fingerprints are often used for the conclusive identification of individuals. 

WHY ARE FINGERPRINTS UNIQUE?
Everyone, even twins, have different fingerprints. This is because the tiny ridges and grooves on our fingertips that make up our fingerprints are formed by both generic and environmental factors – both before and after we are born. 

Fingerprints are partially genetic. This means that parents pass on certain qualities of their fingerprints to their children. But fingerprints are also largely influenced by the conditions inside the womb where the fetus develops before being born. The position of the fetus and the pressure of the amniotic fluid surrounding the baby cause t layer of cells in the skin that makes the fingerprint to bend, warp and buckle in random ways while the skin cell are first forming . These variables are slightly different for each baby, and thus all fingerprints are somewhat random and all unique. In addition, even after people are born, their fingerprints can change. For example, an injury can form a scar that permanently changes the fingerprint. 

Fingerprints  facts
• A person fingerprints are formed five months before they are born, and they do not change during life. 
• Experts can analyze these fingerprints to match them with suspects in a crime.
• No two humans have the same pattern of ten fingerprints, not even twins.

Arches – these are ridges that change direction only once from one side of the finger to the other. This is the simplest pattern of fingerprints.
Loops – these form when adjacent arch system come together,  forming a patten called Triadius. There is a curved end of the loop and an open end. The open end can point either toward the thumb side of the hand or the opposite side . 
Whorls – when the ridges form a circular pattern with central core, and with tow Triradii, the pattern is called a whorl. 

FINGER PRINT INFORMATION
* Fingerprints are fully formed at about 7 months of fetus development and finger ridge  configurations do not change throughout the life of an individual except due to accidents such as bruises and cuts on the fingertips.
* Unrelated persons of the same race have very little generic emilarity in their finger prints.
* Parent and child have some generic similarity as they share half the genes.
* Siblings have more similarity
* The maximum generic similarity is observed in Monozygotic identical twins. 

ANALYZE YOUR FINGER PRINTS
According to the “Henry Classification System” used by the FBI, there are eight different basic fingerprint types seen here.

This chart will help you compare your prints with different types. There are 3 main finger prints patterns: Arches, Loops and Whorls.

Arches are found in about 5% of fingerprints patterns encountered.
Loops occur in about 60-70% of fingerprint patterns encountered.
Whorls are seen in about 25-35% of fingerprint patterns encounted.
