The Y chromosome is getting shorter and shorter, will men disappear after 5 million years?

Although the Y chromosome is unique to males, females do not have a Y chromosome in their chromosomes, and they can still survive, and there may be other chromosomes that are updated in the future, so that the Y chromosome will be withdrawn from history, and men will still survive.

It won't disappear, the Y chromosome is male-specific, but now that women become males through medical means, they don't generate Y chromosomes in their bodies, and transsexuals can also marry wives and have children, so I think that the getting shorter and shorter Y chromosomes should not have much to do with the disappearance of males.

It won't disappear, the chromosomes are uncontrollable, sometimes the genes will mutate, and the man will disappear after 5 million years, and there is so much time that there is no need to think about this problem at all.

It will not disappear, the development of men to the present, the genes are like this, even if they are getting shorter and shorter, they will not reach the state of complete disappearance, which will not change for tens of millions of years.

According to human scientific research, men will indeed disappear after 5 million years, but this is too long ago, and we don't need to worry about it at all.

These judgments are also something we can't judge, which is also a question for many scientists, because many things in this world on the earth cannot be decided, there is no accurate conclusion, and many people say that although organisms have no Y chromosome, only there is an X chromosome, but there will also be gender differences, etc., this is just our guess.

Some experts have said that 300 million years ago, the genes of the Y chromosome had more than 1,400 genes, but now there are only 45 genes, and more than 1,400 genes are embarrassing. However, some people say that the remaining 45 genes have been precipitated and stabilized, and there will be no more degeneration.

Although the average male height has increased by about 15 centimeters over the past 200 years, the length of the Y chromosome, which determines male sex, has been decreasing. As early as more than 16 million years ago, the X and Y chromosomes had a common **, each with 1669 genes, and the current Y chromosome is only 1 3 times the length of the X chromosome.

What if the Y chromosome disappears? For mammals, the disappearance of the Y chromosome means the extinction of the male individual and the entire species. Are there any cases where the Y chromosome disappears and the species continues to survive?

The mole-shaped vole, as well as two species of Japanese rats, are typical examples. In the process of evolution, the Y chromosome was inadvertently lost, and the gene that determined the other species also disappeared, but the gene CBX2 on chromosome 2 of this species played a role in determining the sex of males. Perhaps this news will restore humanity's confidence.

Chromosomal shortening is not directly related to male extinction.

There will definitely be some and there will definitely be men, don't worry.

Go ahead and make a few more male friends while you're young!

This situation is completely overthought and will not happen.

It's possible, but it shouldn't be without men.

There will definitely be men in the future.

This has to be taken seriously, quite possibly.

There should still be it, and it won't go away.

Scientists have found that the Y chromosome is disappearing, will there be males in the future?

It can only be said that there are fewer men, why can't there be no men?

There will definitely be somewhat, and there will definitely be men.

It shouldn't be too short.

Men will still be male in the future, but shortened chromosomes should reduce the chance of having a boy.

It shows that the number of men in the future may be less and less, and the future male development may be worse and worse, which leads to the better the genes of women, men should strengthen the protection of their personal bodies, but also strengthen the maintenance of genes, so as to better promote the development of genes.

Be sure to improve your quality of life, don't smoke, don't drink, don't stay up late, then exercise, eat more fruits and vegetables, and get rid of bad habits.
