I wonder if the offspring of smart girls are really smart.

The genetic gene ZT of IQ

IQ genetic gene

Very interesting.

It is said that the eight pairs of genes that determine IQ are all located on the X chromosome, and then the boy is XY.

X comes from mother,

Y is from dad.

So the IQ of boys is inherited from their mothers.

Then the girl is X X, so half of the IQ of the girl is influenced by her parents.

Then, because the IQ of girls is influenced by both father and mother, there will be a neutralization effect.

Therefore, the distribution of female students' IQ will be normal, inverted bell-shaped, with the most in the middle.

More sides, less.

Then, because boys are completely influenced by only one side, the distribution of boys' IQ will be biased towards two extremes.

In other words, boys are more talented, but at the same time, there are many boys among fools.

What does this story tell us?

1, "To judge whether a boy is smart or not, just look at his mother. 」

2. Then we use probability to calculate: the probability of having a boy = 1/2, and the probability of having a girl = 1/2.

When giving birth to a boy, the mother's influence on the boy's IQ = 1.

When giving birth to a girl, the influence of the mother on the IQ of the girl = 1/2.

So the ratio of the influence (expectation) of mother and father on the IQ of the next generation is:

1 * 1/2+ 1/2 * 1/2: 0 * 1/2+ 1/2 = 0.75: 0.25 =

So, if you:

1, it's a boy, if you think you are stupid. You must marry a smart girl!

In this way, your child still has a 75% chance to turn over and life is still full of hope.

2. It's a girl. If you think you are stupid, that's too bad ~

Because, you have a 75% chance to turn over other people's dishes. ....

When you see a boy is smart, the probability that his father is smart is 0%.

(It should be said that even if his father is smart, it doesn't matter to him), but the probability that his mother is smart is 100%.

Therefore, if you are considering marrying a very smart boy, you should be careful of his mother, who may be a calculating mother-in-law.

On the other hand, when you see a boy is stupid, yes, he is usually rich, which is God's arrangement.

In order not to let mankind perish, the emperor will make stupid people rich so that he can marry smart girls.

In short, when you see a rich but stupid boy, don't hesitate to marry him! ! !

Don't think that you are doing it for his money, you should tell yourself that you are doing it to improve the genes of future human beings.

This is actually an imprecise statement. Intelligence actually comes from diligence, from family environment, from training and exercise. High IQ is by no means hereditary.

I have been pursuing and exploring since I was a child. In fact, which child is not an explorer, inventor and the most curious person? Parents gave their children too many restrictions when they were young, which virtually killed their precious genius temperament. On the contrary, if we give him heuristic education and give him enough nutrition and a good environment, there may be more children with high IQ in this world.

——————————————————————————————

Personally, I feel that I am a girl.

My looks are more inherited from my father.

The figure is inherited from the mother.

Personality is inherited from both of them.

An impatient person, a chronic person, so sometimes I am more anxious than anyone else, and sometimes I am slower than anyone else.

As for IQ

I think it has something to do with heredity.

But no matter how good the brain is, it will rust if you don't exercise the day after tomorrow.

There are other factors.

For example, I have a relative.

The child is a boy.
