How does a person s fingerprint make it different for everyone?

As the saying goes, "No two leaves are exactly the same", and accordingly, no two people in the world are exactly the same, and even twins are very different. Even if two people who look very similar have different fingerprints, how do people make their fingerprints different? This is determined by the genes of our parents, and our fingerprints are already formed when we are still in our mother's womb.

Each of us is still in the mother's womb is determined what kind of fingerprint will come out in the future, this fingerprint is determined by the genes of father and mother, because the genes of parents are also unique, so the fingerprints they give us will also be unique in this world. Once our fingerprints are formed in our mother's womb, they cannot be changed, and even if they are worn out in real life, they will still return to their original appearance.

With the continuous development of science and technology, fingerprints have received more and more attention and attention in modern people's lives, and fingerprints can solve many difficult puzzles in our lives. If the police uncle can distinguish your authenticity through the fingerprints of the suspect when handling the case, even if two very similar twin brothers want to help scapego, they will be found out. In addition, fingerprints have also facilitated our lives, we only need to put our fingers on the punch card machine to punch in and out of work, and we no longer have to manually register as many years ago.

In addition to these, fingerprints have greatly improved the safety factor of our lives. Nowadays, many people will set a fingerprint unlock on their dream weaving mobile phone, and the payment page can only be opened with their own fingerprint, which brings a great guarantee to our privacy and property security. Just because fingerprints are inherited from our parents, everyone has their own unique fingerprints, so fingerprints are very useful in our lives, and we should make good use of this resource to make our lives more colorful.

Because a person's fingerprint is determined by a person's genes, in this case, everyone's fingerprint is different. Because the proteins expressed by genes are completely different.

Human fingerprints are innate, fingerprints themselves are unique, each individual is different, and this can be obtained without doing anything else.

This is determined by our DNA**, so basically you can't find the same fingerprint.

Why everyone's fingerprints are different

The mysteries of the human body are like the mysteries of the world, endless, confusing, waiting for people to explore one by one. For example, many people wonder why people's fingerprints are different, and no matter what, they can't be changed. Dear children, do you have the same questions?

Next, I will talk to you about this little knowledge, you have to listen carefully.

Fingerprints are genetically determined, and once formed, they become a lifelong marker for a person. Even if the finger surface is corroded with fire, knife, or chemical, the fingerprint remains unchanged after the wound heals. Fingerprints are composed of different lengths, shapes, thicknesses, and structures, and are divided into three basic types: buckets, kei, and bows.

Fingerprints can reveal genetic patterns and signs of certain diseases. If there is a congenital dementia, the fingerprints of such patients are unusual. Therefore, scientists are constantly exploring the use of fingerprints, palm prints, and plantar prints to diagnose diseases.

In addition, scientists have developed a "fingerprint key", which is a human fingerprint. With the push of a finger on the computer set up on the door, the door opens automatically.

Fingerprints are a characteristic of a person, so do you know why fingerprints are all different?

Why everyone's fingerprints are different

01 The primary reason for the difference in fingerprints is that the genetic material is different, and each person has a specific gene, so the fingerprint pattern formed is also unique.

02 Fingerprints are not only affected by congenital heredity, but also can be changed by friction when the fingerprints are not finalized in infancy, but there will be no two identical fingerprints.

03 There are three types of human fingerprint models, which are ring, bow and spiral, which only shows the general pattern of fingerprints, and it is still impossible to change the genetic material to cultivate the same fingerprint at the current scientific level.

04 So far, it has not been found that different people have the same fingerprints, and each person's fingerprints can represent him, so it is also very helpful for the investigation of **.

A fingerprint is a strange spiral pattern in nature. Humans all have fingerprints, and they can easily identify different people. This is because each person's fingerprints are unique, so how are they formed and why do they reflect the information?

The inner surface of our palms, fingers, feet, and toes have uneven lines, and the generation of these lines is extremely beneficial to us, because their presence increases the friction on the surface, making it easy for humans to grasp heavy objects with their hands. In the same way, the pattern on the tires of a car is also designed to increase the friction on the ground.

As with every component of the human body, the formation of these lines is the result of a combination of genetic and environmental factors. Genetics in DNA gives the overall "command" of how to produce the fetus during the formative stage, but the formation of its specific subtleties is a random event. The specific position in the womb at a particular time of the fetus, as well as the density of the surrounding amniotic fluid and other substances, determine the differences in the texture of each individual.

In addition to the myriad genetic factors that determine how a person will be "made", there are also many environmental factors that influence the formation of fingerprints, such as the weather. The whole process of fingerprint formation is very disorderly, and in fact, in the long history of mankind, it is impossible to form two identical fingerprint patterns. Thus, a fingerprint can serve as a special marker for a person, even if it is two identical twins.

Two fingerprints that look roughly similar can also be identified by experts or special software. This is the basic idea of fingerprint analysis, whether in criminal investigation or security, the job of a fingerprint reader is to replace an expert, collect samples and compare them with samples that have already been recorded.

1. One type of fingerprint is bucket type, which is composed of many concentric circles or spiral lines, with concentric circles or rolling letter spiral lines, which looks like a whirlpool in water.

2 Fingerprint type: A basket type, carrying a cherry blossom pattern similar to a dustpan, with one side open.

3. One type of fingerprint is bow type. Some of them are shaped like bows.

4. The first type is obvious lines, which are lines that can be seen visually. For example, if the hand is stained with paint, blood, ink and other items, it is usually printed on the fingerprint card to become the basic information.

5. The second type is the molding pattern, which refers to the fingerprints that appear on soft materials, such as candles and clay embossed on soft materials.

6. The third type is latent fingerprints, which are the fingerprint lines formed by the transfer of natural secretions such as sweat from the body, which are not easy to find visually, and are the most common fingerprints at the crime scene. Latent fingerprints are often left by fingers that come into contact with grease, sweat or dust, and then come into contact with a clean surface, although these fingerprints cannot be seen by the naked eye, but can be shown by special methods and the use of some special chemical agents.

It is determined by genetic inheritance, each person has different chromosomes, and the gene excitation controls the fingerprint of the person, and the arrangement of the particles on the ** is not the same as the allergenic substance, which forms such a situation.

Specifically, it is formed due to each person's physical factors and genetic factors. It is formed by the combination of genetic factors and environmental factors.

Because everyone's genes are different, and each freshman with Zheng Erqiao's imitation is born, his hands are clenched, so everyone's fingerprints are different.
