The discovery denies the possibility of men going to be extinct

A recent study has caused a stir when it comes to claiming that Y chromosomes are on the decline, implying that men are at risk of near-extinction. However, new discoveries by US scientists have denied this.

According to Nature, experts from the Whitehead Biomedical Research Institute in Massachusetts, USA discovered that, instead of being degraded, Y chromosomes have preserved a small genome over millions of years, helping to ensure Men's existence. The genes involved in this Y chromosome play an essential role in shaping the health and disease differences between the sexes.

Professor David Page, a member of the research team, emphasized: "There are more than 10 genes preserved on Y chromosomes, expressed in cells and tissues throughout the body. These are genes involved in encoding and interpreting the entire genome ".

Professor Page stated that his work and his colleagues have proved that the "Rotten Y chromosome" is wrong. This misconception stems from the argument that the original 1,400 Y-gene gene has fallen to only 45 genes over the past 300 years and that trend will continue until the Y chromosome disappears, causing the herd to he extinct.

For more than a decade, Page's research team has been testing the statement. The loss of content on the Y chromosome is undisputed and the researchers found that the Y chromosome preserved only 19 genes out of a total of 600 genes shared with the partner - the X chromosome of women.

However, by comparing the Y chromosome gene sequence in humans with Y chromosomes in chimpanzees and brown monkeys, they found that Y chromosomes lost only one gene passed down by their ancestors over the past 25 million years. The team also found that in other mammals, Y's genome is widely expressed and has a partner gene in chromosome X.

According to Dr. Winston Bellott, Professor Page's partner, the evolutionary process shows that the remaining genes of Y chromosomes are really important to the survival of men, because they have been selected and purified by the time. time.
