What does it mean for scientists to find that the Y chromosome is disappearing?

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

It means that much later in the future there may not be men, only women.

The Y chromosome is the determining chromosome, and if the Y chromosome disappears, the male may also disappear.

Evolve. Because scientists have found that the Y chromosome is disappearing, it means that human beings are constantly following the environment and constantly evolving.

Because the Y chromosome determines the sex of a human being, if the Y chromosome disappears, then a human being cannot give birth to a male human.

If the outer chromosomes of humans disappear, then all children born will be girls, which will cause social unrest.

When the Y chromosome disappears, all newborns born become women, and men disappear.

The Y chromosome is easy to inherit diseases, and it will also inherit some advantages and characteristics, and it will also inherit a certain appearance, it will have a high heritability, and if the Y chromosome and the X chromosome are combined, it will be a boy.

What I understand is that the Y chromosome determines the sex of boys and girls, determines the genes of development, determines the health of the body, determines your IQ, and determines the disease of the body.

The Y chromosome is transmitted from male to female. In the same family, all Y chromosomes are the same. And the exosomes have increased elevated genes. If the Y chromosome is good. The height will be higher.

The Y chromosome is only present in males, the Y chromosome gene can only be passed from the male in the parent z to the male of the offspring, it is able to determine the sex of the fetus, it is the carrier of the genetic material present in the nucleus.

The Y chromosome is decreasing in males.

The study found that the human Y chromosome originally had 1438 genes, most of which were lost during evolution, and there are currently only 86 genes. As a result, there are concerns that sex chromosomes such as the male Y chromosome will eventually disappear.

So the researchers studied this, and the research object was the W chromosome of the hen, just like the human sex chromosome has XY and XX, the sex chromosome of the chicken can also be divided into ZW and ZZ two; But in contrast to humans, the ZW type is a hen and the ZZ type is a rooster.

The researchers analyzed the transmission of genes in the sex chromosomes and the link to fertility. The results show that although these chromosomes have shortened over millions of years and many of the original genes have been lost, the remaining genes are important for fertility and are unlikely to disappear.

The W chromosome of a hen is very similar to the Y chromosome of a human male and is only present in one sex. These chromosomes cannot be recombined during sexual reproduction, while genes from other chromosomes are recombined, making evolutionary selection more efficient and helping to reduce harmful variation.

A study of the W chromosome in chickens.

In the study, scientists compared the DNA on the W chromosome of different breeds of chickens and measured their fertility by counting the number of eggs. Two breeds, the Minorca and Leheng chickens, lay more than 250 eggs per year, while the other two breeds, the Japanese long-tailed chicken and the ancient English fighting, were bred for their male traits such as fighting ability and plume-crowned feathers.

Scientists compared the genetic information of these chickens and analyzed the ancestors of the domestic chicken, the red junglefowl.

The researchers measured the expression levels of W-linked genes in all chicken breeds, and the results showed that the expression of almost all W-linked genes was enhanced in egg breeds that were selected for egg production. At the same time, in breeds with male traits such as fighting ability and feathers, the expression of W chromosome genes was missing.

This means that female selection based on fecundity shapes the W chromosome, and that the chromosome has a way to cope with selection despite the lack of recombination.

Y and W chromosomes are very important for fecundity. The ability to evolve W-linked genes is the key to their preservation, which means that chromosomes such as Y and W will persist for a long time.

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

The human Y chromosome is gradually disappearing, will males disappear in the future?

Recently, some studies have shown that the chromosome Y in males is gradually disappearing, and they speculate that after 5myas, the human male sex chromosome Y will disappear completely, and humans will become asexual reproduction, and females will reproduce on their own. They say it's a self-repairing function of the Y chromosome that causes the Y chromosome to start getting shorter. However, in a person's life, due to the continuous replication of cells, the error of each replication, and the human replication mechanism is no telomere replication, so the DNA in the chromosome will become shorter every time it is replicated, which is one of the reasons why the body function of the aging body becomes worse in the end, if it can be replicated 100% without loss, then it will not age, and it will not die naturally.

No, but mutations are possible.

In recent years, there has been a theory that the Y chromosome is dying out. The Y chromosome is a chromosome that is unique to males, and each male's Y chromosome is inherited entirely from the father's side. Some scientists suspect that the single Y chromosome is not able to maintain its stability by exchanging genes with its "companion" chromosomes like other chromosomes, which has led to the loss of genes and eventually extinction of the Y chromosome over the course of tens of thousands of years of evolution.

The average male height has increased by about 15 centimeters globally, but the length of the Y chromosome, which determines male sex, is shrinking.

Because the ratio of men to women has begun to skew, there is a trend of more girls than boys.

As humans progress, 1 genes will change to a certain extent.

Because now, the ratio of men to women is gradually skewing towards the side of girls.

Shocked, there are fewer and fewer genes on the Y chromosome, and males will eventually disappear?

Because the ratio of men to women is almost out of balance.

Because now there are fewer and fewer men.

Because there are fewer genes on it.

This region of the Y chromosome can repair itself without the help of a companion. However, another region of the Y chromosome, called "X degeneration", does not have a palindromic structure, so it is still possible that the prediction of the death of the Y chromosome will come true.

The human Y chromosome is gradually disappearing, will males disappear in the future?
