Human beings can reproduce because of the inheritance of genes, and will acquired changes affect the

Human beings can reproduce because of the inheritance of genes, so we often find that a person's personality is very similar to his parents, either like a mother, or like a father, so people think that genes determine everything, but such a statement is too absolute, congenital is important, but some acquired behaviors will also have a certain impact on a person's genes and personality. <

Many people will be troubled because their original family or their parents' personalities have very obvious defects, this is very unnecessary, because we have to learn to accept it, we can't change others, we can only change ourselves, we have to choose better genes for our next generation, this is what we can choose, we don't have to worry about what we can't do, we have to change what we can do. <>

There are many students who come out of the poor, how good are their genes? I don't think so. If their genes are good enough, their parents should have gone out of the mountains to create a good learning environment for their children, but they didn't, so these poor students can only study under very bad conditions, but they still go to Beijing and Shanghai step by step through their own efforts, and take root and live in these big cities.

If genes are everything, violent suspects don't deserve to have children, or their children should be arrested because they have the same genetic problems. Therefore, this statement cannot be too absolute, we must believe that people's character is originally on the positive side, but it is just distorted at a certain critical juncture, which is an acquired influence. <>

There is nothing in this world that cannot be changedSo we have to change our mentality, make ourselves more calm, be able to face some problems normally, and believe in our own abilities.

Yes, acquired changes are likely to affect the inheritance of genes, and once genes are changed, they will be greatly affected.

It should be, otherwise how would we be able to transition from apes to humans, all of which are genetic. is very important.

In short, it is a rapidly changing environment.

First, the gradual change is basically a quantitative change process, which is not obvious. Prepare for devastating natural disasters such as volcanoes, flash floods, etc. Excellent genes are screened and retained.

Third, in the process of bearing two, the gene may be mutated. Individuals who have undergone mutations have to adapt to the changed environment, some adapting and some not. The adaptors are retained, and the unfit ones are eliminated.

Fourth, the development of science and technology, the irradiation of rays, space travel, etc., genetic mutations, and accept the test of three.

Fifth, with the development of science and technology, the development of genetic engineering, that is, the change of genes that is considered to make the change of human genes more complicated.

It's complicated! Complex! It's hard to say in a few words! Thank you for your understanding!

There are many reasons, physical factors, chemical factors, biological factors, and so on.

Physical factors include radiation, etc.; There are many chemical factors, such as benzene compounds; Biological factors are only some viral infections.

From ancient emperors seeking immortality to modern scientists studying human genes, human beings have a natural attachment to immortality. Birth, old age, sickness and death are originally natural laws, but what will happen when science breaks the laws of human genes and human life expectancy is extended in the future? Would you choose to change your genes to prolong your life?

Summary. If you ignore random mutations in DNA, for males, then it is true that your Y chromosome is no different from the Y chromosome of your male ancestors thousands of years ago. The Y chromosome is a sex-determining chromosome, and its impact on appearance is negligible, and if the impact is significant, the result will be quite bad, because it means that even if a series of male ancestors are desperately trying to marry beautiful women, they will not be able to improve the appearance and appearance of male offspring.

Is it scientific to compare the genes of human lineage transmission thousands of years apart?

Scientific.

If you ignore random mutations in DNA, for males, then it is true that your Y chromosome is no different from the Y chromosome of your male ancestors thousands of years ago. The Y chromosome is a sex-determining chromosome, and its impact on appearance is negligible, and if the impact is significant, the result will be quite bad, because it means that even if the male ancestors of the Yiwu Peng Finger series are desperately trying to marry beautiful women, they will not be able to improve the appearance and appearance of the male posterior.

The comparison of genes transmitted by human lineage, which is separated by thousands of years, is still partly scientific.

Because genetic variation is very rare, human gene transmission is still very regular after thousands of years.

The DNA is very stable, and reproductive isolation occurs after about 2,000 generations, about 40,000 years or so. The variation produced by thousands of years of time is negligible.

Hope mine can help you.

If you don't mind, move your little hands, give a thumbs up, and wish you a happy life.

A few days ago, I talked to my son **, and my son said that in the biology class, the teacher told everyone that egg donation is a very painful thing, and asked everyone not to try. When his son heard this, he was very excited because he found out that there was such a good way to pass on his genes in large quantities. He said that if you can donate 60 eggs, what a great thing it is.

For this, he will not stop even paying the price with his life. You must know that it is just normal to get married and have children, and a person can pass on two or three at most. And through egg donation, you can pass on your own reserve genes in large quantities.

Listening to what he said, I really couldn't laugh or cry. I expressed that my life is the most precious, and I am not willing to give up my life for the sake of genetic inheritance. My son strongly disagreed with me and tried to convince me, crying and getting emotional as he spoke.

I asked him why he was crying, what did this touch? The son said, "It's not important."

What matters is what the genes pass on.

Looking back at my conversation with him, I think I still had a preconceived idea that his ideas were too ridiculous and tried to convince him. Actually, it would be better to listen, to repeat what I had heard, and to ask him with curiosity why he thought that genetic inheritance was so important.

Now that I think about it, is it because he thinks it's a great idea, and everyone laughs at it when he expresses it at school? He was very eager to be recognized.

Adapting to the environment is changing little by little, not overnight...
