I still remember how satisfied my mother and grandma were after seeing the fingerprints on my hands. At that time, I already had a certain memory ability. After repeated confirmation by them, they confirmed that among the 10 fingers on my hands, there were All 9 patterns are snails!
As the saying goes, "Nine fights and ten fights lead to more success." The words "dou" and "luo" actually mean "luoluo". Although they have not received much education and know that such folk rumors have little credibility, they still think it is a "good sign."
Of course, as more and more people receive higher education, whether a child’s fingerprint is a snail or a dustpan is just for fun, because a person’s lifetime wealth is not limited to What is given to you by your family when you are born, you have to fight for it on your own. You will not be able to lie down just because your fingerprints have 9 or 10 snails.
However, when the teams from Fudan University and the Chinese Academy of Sciences were studying fingerprints recently, they revealed some genetic mysteries that can be discovered through fingerprints. They mainly involve three major aspects, which can be said to be relevant to each of us. relation. Relevant research results have been published in "Cell". Most people may have never heard of it, but this is an internationally authoritative academic journal. During the entire research process, not only a powerful research team such as academicians from Fudan University and the Chinese Academy of Sciences, but also In collaboration with more than a dozen foreign scientific research institutions, let’s take a look at the specific major discoveries!
"Bucket" and "dustpan" have nothing to do with skin development. Fingerprint patterns are formed early in embryonic development, and their type will not change after birth!
Researchers said that Asians as a whole have "less skip type and more bucket type", and some people may also have "bow type". This time, researchers have conducted the largest study of fingerprint patterns to date. Through genome association analysis, they found that 43 human genetic loci are related to the fingerprint patterns of our hands, but none of them show It is related to skin development. Even though our fingerprints are grown on the skin, they are actually closely related to the development and function of the limbs.
To be more specific, the length ratio of a person’s fingers is related to the fingerprint pattern. If a person’s little finger is longer, his palm length will be relatively shorter, and the length of both hands will be shorter. Most of the ten fingers have bucket-shaped patterns. If the distal knuckle of your index finger looks longer, it usually means there are more dustpan-shaped patterns.
There is a correlation between striae phenotype and congenital genetic diseases. Is it true that "palm reading is a disease"?
Researchers said that the scientific community has discovered a basic fact before, that is, many congenital genetic diseases are related to the striae phenotype. To give a specific example: like Tang Patients with Syndrome's syndrome may have body striae phenotypes such as ball marks on the big toes and broken palms.
Many people may not know that as early as the 1960s, studies have found that many leukemia patients have more bucket-shaped fingerprint patterns, but no one knows why. so.
This time’s research results have laid a theoretical foundation for the relationship between diseases and fingerprint patterns. The researchers said that it is also possible to “recognize diseases by looking at hands” in the future. Moreover, the research team has obtained an invention patent, that is, "Down syndrome skin pattern assisted screening", which is the first new system to assist in the screening of Down syndrome based on skin pattern phenotype.
In the world's first "Human Phenotype Navigation Map", a team of Chinese scientists discovered more than 1.5 million strong associations, most of which were discovered for the first time, and 39% of them exceeded field!
I believe everyone knows how powerful genes are. Just as when the same virus infects different subjects, some people will die, but some people will have no obvious symptoms.
Scientists study the relationship between fingerprint patterns and individual limb phenotypes. In fact, they are studying how the internal code of genes communicates with genes in a specific environment, and then what kind of expression is expressed externally. type characteristics.
There are hundreds of millions of people on the earth, but every person in the world, including those who have passed away and those who are living today, has always had a unique fingerprint. But so far, We don't understand all the reasons behind this phenomenon. Researchers will further expand the group participating in the study and more deeply uncover some phenotypic characteristics that may not have been discovered by scientists but are related to human conditions!
