As the saying goes, "Nine fights and ten fights are more", "Nine fights and nine fights, being a satrap, ten fights and ten wins", "Nine fights and one dustpan, eat dry at a time", and the proverb "fight" and "Luo" actually means "snail". Although they don't have much education and know that this kind of folk rumor is not credible, they still think it is a "good sign."
Of course, with more and more people receiving higher education, it is just for fun that children's fingerprints are snails or dustpans, because a person's wealth in his life is earned by himself after birth, and he will not lie flat just because his fingerprints are nine or 10 snails.
But recently, when Fudan and the Chinese Academy of Sciences team were studying fingerprints, they uncovered some genetic mysteries that can be discovered through fingerprints, mainly involving three major aspects, which can be said to be related to each of us. Related research results are published in Cell, which most people may not have heard of, but it is an international authoritative academic journal. In the whole research process, there are not only strong research teams such as Fudan University and academicians of Chinese Academy of Sciences, but also more than a dozen foreign scientific research institutions. Let's take a look at the specific major findings!
"Dou" and "dustpan" have nothing to do with skin development. Fingerprint patterns are formed as early as embryonic development, and their types will not change after birth!
Researchers say that Asians as a whole are "less baskets and more barrels", and some people may be "bow-shaped". This time, the researchers' research on fingerprint patterns can be said to be the largest so far. Through genome association analysis, it is found that 43 gene loci of human beings are related to the fingerprint patterns of our hands, but none of them are related to skin development. Even if our fingerprints grow on the skin, they are actually closely related to the development and function of limbs.
More specifically, the proportion of a person's finger length is related to the fingerprint pattern. If a person's little finger is long, then the length of his palm will be relatively short, and most of the ten fingers of his hands are bucket-shaped patterns. If the knuckles at the distal end of your index finger look relatively long, they are usually more dustpan-shaped.
Dermatoglyphic phenotype is related to congenital genetic diseases. "Palming is a disease" or is it true?
The researchers said that before this, the scientific community had discovered a basic fact that many congenital genetic diseases were related to dermatoglyphic phenotype. Specifically, for example, patients with Down syndrome may have body dermatoglyphic phenotypes such as arched ball lines on toes and broken palms.
Many people may not know that as early as the 1960s, studies found that many leukemia patients had more barrel fingerprints, but no one knew why.
The research results this time laid a theoretical foundation for the correlation between diseases and fingerprints. The researchers said that it is also possible to achieve "seeing a doctor by hand" in the future. Moreover, the research team has obtained the invention patent, namely "Down's Syndrome Dermatoglyphic Auxiliary Screening", which is the first new system to screen Down's Syndrome from dermatoglyphic phenotype.
In the world's first "Navigation Atlas of Human Phenotype Group", the team of Chinese scientists found more than 6,543,8+0.5 million strong associations, most of which were discovered for the first time, and 39% of the strong associations even crossed the field!
How powerful the gene is, I believe no one will not know it. Just like the same virus infects different objects, some people will die, while others have no obvious symptoms. Scientists study the relationship between fingerprint patterns and individual limb phenotypes, in fact, they are studying how internal codes such as genes communicate with genes in a specific environment, and then what phenotypic characteristics are displayed externally.
There are hundreds of millions of people on the earth, but everyone in the world, including the dead and the living, has a unique fingerprint, but so far we have not figured out all the reasons behind this phenomenon. Researchers will further expand the groups participating in the research and reveal some phenotypic features that may not have been discovered by scientists, but are related to the human condition!
