MAOA gene is suspected of "insulting China"

When it was dry and it didn't rain, Liu Bei was in a hurry and ordered the whole people to ban brewing. Even those who had brewing tools were arrested and sent to prison.

One day, while Liu Bei and the mayor Jian Yong were on patrol, they saw a man and a woman walking. Jian Yong said, master! These two dog men and women are going to commit adultery, and I want to catch them!

Hearing this, Liu Bei said, Oh, aren't you fooling around? The two of them walked very well. Which dog eye saw them clap for love in public? How can we become the Lord of benevolence and righteousness?

Jian Yong said, I'm not fooling around. Aren't they all covered in lewd things? Isn't it a slap in the face to have something dirty? Is it not adultery? Liu Bei realized this. Oh, you're playing me! All right, let those people go

A few days later, Jian Yong came to ask for instructions. Master, I caught a big hooligan in Shu and got a little red! Now the food market is naked and open to the public. Please come and study!

Liu Bei ran to have a look.

Fuck!

What a demon!

Bullwhip!

It's amazing!

Cann't catch up with ed,

More than Xu Jinjiang!

Return to absolute being, eyes turn, there! Interrogate hooligans face to face, I ask you, men are like demons beforehand and Buddha afterwards. How can you make many people shine in one night? What is the secret? Say it. I'm in charge with you.

I cried a little red in Shu, my sage, I am a family of poets and calligraphers, and all the eighteenth generations were good people, but this talent is really beyond my control. I really don't want to. I'm tired. I really can't live, because it's dragging me down!

Big Ear Thief waved his hand. I'm not that smart, so you won't die! I'm not guilty of shooting you! Somebody please. Send him to the painting academy to be a male model!

Jian Yong received it, stopped and said, Master, what's wrong with you? This is the first rogue in Sichuan! Liu Bei scolded, what do you know? He's a natural pervert. He looks like this, and his big head is controlled by his small head! If you have such a small head, I will shoot you innocent!

Get off and get home safely.

Whether Shu later passed a law to punish prostitutes according to the size of their small heads is not recorded in the history books. However, Mr. Xi Lanhua knows that in the decadent western capitalist countries, there are indeed judges who listen to the defense's statement that murderers are vicious, but it is precisely because of the "sage gene" in the body that anger starts from the heart and evil comes from the heart, and his hands are completely out of control, so that he kills people and even gets a lighter sentence.

This "sage gene" is called Mao 'a gene, or more accurately, MAO-A gene. This gene encodes an enzyme called MAOA, which removes neurotransmitters such as dopamine, norepinephrine and serotonin.

Many people's eyes must light up when they see dopamine, norepinephrine and serotonin. Isn't this something that excites me and makes me feel good? Why does MAOA enzyme fight them?

Simply put, life must die. No matter how valuable the banknotes issued by banks are, they will eventually be recycled and destroyed; Otherwise, the money will be worthless and inflation will occur. The same is true of neurotransmitters, which are destined to be removed by MAOA enzymes and other methods from the moment they are produced; Otherwise, the more you accumulate, the more you feel. How can you do things?

Ok, in the early 1990s, some people in the Netherlands studied a group of criminals and found that their MAOA genes were somewhat different-they only produced a few MAOA enzymes. Therefore, this MAOA gene is called MAOA-L gene, and the corresponding one is called MAOA-H gene. L and h naturally mean low and high here.

Since MAOA-L gene has been found in criminals, we should find a reason. Clap your head, got it!

This MAOA-L gene only produces a few MAOA enzymes, which means that dopamine, norepinephrine and serotonin will accumulate in large quantities. So will this guy be happy? Oh, no, this is a criminal. Impulsive violence, of course!

Wonderful! This is the "sage gene"!

Then it was found that about 34% of whites in Europe carried the MAOA-L gene, while as many as 56% of Maori in New Zealand carried the MAOA-L gene.

Maori, isn't that a savage who eats and drinks blood? No wonder. . .

However, some people in Taiwan Province have made an analysis, and now it is found that the proportion of the Han population carrying MAOA-L gene is 77%. . .

It turns out that the most savage person in the world is the Han nationality in China?

What a fucking insult to China!

Of course, it is not insulting for some iron-blooded teenagers to see Pu Daxi running wildly. How can this be an insult to China? This proves that my Han nationality is the bravest nation in the world! Let me be a strong person, even if I am far away, I will be punished!

It is obviously a joke to attribute personal impulses and crimes, even extremely vague national characteristics, to the MAOA gene, which is no more reasonable than Liu Huangshu's forgiving the big head (edited by Broccoli Jun). People's personality is influenced by many factors, and the destruction of neurotransmitters is not only based on MAOA gene, but also based on MAO B gene.

Finally, does MAOA gene have anything to do with autism?

Simply put, if half or even more people carry the MAOA-L gene, it is equivalent to finding the relationship between it and autism. There is no explanation except stubbornness.

However, it is found that a very small number of people will be born with the deletion of MAOA gene, which is characterized by low IQ (generally around 85), impulsive behavior, sleep disorders, mood swings and so on. This disease is called Bruner's syndrome. Animal experiments also show that mice lacking MAOA and/or MAOB genes will show some symptoms similar to autism. However, due to insufficient evidence, both MAOA gene and MAOB gene are classified into the third category in SAFIR autism gene bank, that is to say, their deletion or mutation may be related to autism, but the evidence is insufficient and they are temporarily classified as suspected.
