Males can die out due to Y-chromosome failure

After 180 million years, the Y chromosome continues to deteriorate, leaving the future of men uncertain.

Scientists warn that the male species may become extinct as Y chromosomes begin to malfunction.

The Daily Star writes about it.

The sex of both humans and mammals is determined by the X and Y chromosomes, the thread-like structures that contain DNA and proteins in the body. Men have X and Y, and women have two X chromosomes. They make up only 4% of a person's DNA, yet make perhaps the biggest difference in someone's life.

Unfortunately, scientists believe that the number of Y chromosomes is decreasing, which could mean a future without men. The Y-chromosome is tiny, with only 45 genes on it, and only one of them is responsible for male sex.

This was not always the case, because before Y was very similar to X and had about 900 genes. Now their number continues to decrease. Sex chromosomes originally arose from…
