Imagine a world where there will be only women. A world created by them, where they will rule and their own principles will prevail. There will be no men in that world.
Can this happen? It sounds like a dystopia, but science is pointing towards something else.
According to a study published in the 'International Journal of Molecular Sciences', as the world progresses, the size of the Y chromosome in humans is decreasing. A similar study was also published in the prestigious science journal 'Nature'. After these studies, the discussion on the extinction of the Y chromosome has gained momentum.
In fact, chromosomes determine whether a person will be a man or a woman. If there are two X chromosomes (XX) then the gender will be female. If the chromosomes are X and Y (XY) then the gender will be male. Overall, chromosomes are responsible for determining gender.
Based on this study, scientists believe that the way the size of the Y chromosome is decreasing, it can lead to the possibility that one day this chromosome may become completely extinct and men will stop being born on this earth. Then after the last generation of men, the entire human race will also be destroyed.
so today 'health report' We will talk about this study related to Y chromosome. Also, we will know that-
Two species of mice have lost their Y chromosome
In humans and other mammals, the sex of the child is determined by a gene present in the Y chromosome. Therefore, that gene is called the male-determining gene and the Y chromosome is called the male-determining chromosome. This chromosome responsible for sex determination is gradually weakening and it is feared that it will disappear after a few lakh years. This also poses a threat of extinction of the human species. Even before this, the Y chromosome of two types of rat species has become extinct.

All living organisms on earth change with time
All the living beings born on earth undergo some changes with time. These changes come according to the need of that time. Understand it this way that the initial species of humans were like monkeys. They had four legs and a tail. As time passed, the two front legs became hands, the tail became smaller and disappeared. Earlier, all the fingers in the hands and feet were equal. With the passage of time, the fingers which were used less as per the need, became smaller.
These are some of the changes that are visible in our body. While many changes are also happening inside our body at the micro level. One of the important changes among them is that of genes. Many genes present in our Y chromosome are vanishing. Due to this, its size is getting smaller.
What did the study reveal?
According to a study published in the International Journal of Molecular Sciences, a large number of active genes present in the Y chromosome have disappeared in the 170 million years since humans and platypus separated. They have reduced from 900 to just 55. If the rate at which they are disappearing continues, the Y chromosome may disappear completely in the next 10 million years. The study Understand easily through graphic.
This fear of human extinction has sparked debate among scientists. Some scientists believe that the Y chromosome will last indefinitely, while others believe that it will disappear in a few thousand years.
Study done on rats has raised hopes
Researchers led by biologist Asato Kuroiwa at Hokkaido University in Japan found that most of the Y chromosome genes in spiny rats had been transferred from another chromosome.
Researchers found that these mice survived even after the Y chromosome was lost. This is because all the genes present in the Y chromosome were transferred to a third chromosome. This chromosome is present in all male mice, but is absent in females. This seems to be just an evolutionary process. If one chromosome is lost, another male specific chromosome will take its place, that is, a chromosome that will be found only in the male gender.
The will to live is what keeps us alive
Beyond science and spirituality, there is a theory that survival can keep anyone alive. It is our will to live that keeps us alive. At present, the possible loss of the Y chromosome of humans remains a matter of concern. While this research done on mice is also raising hope and expectation. It also suggests that our human species can also potentially develop a new sex-determining gene, which will ensure the continuation of the production of males.
However, many scientists have also warned that such evolutionary changes could lead to the emergence of multiple sex-determination systems in humans. Which could potentially result in the creation of many new species.
Overall, we are going to face an uncertain future about which it is not possible to say anything very precisely. Despite this, this study done on mice provides a ray of hope for human survival and opens new doors for research in sex determination and development.
