The Y chromosome, responsible for determining male sex, has been shrinking over millions of years, leading scientists to wonder if it's eventually disappearing. Compared to other chromosomes, the Y has lost much of its genetic material, which has raised concerns about its long-term survival. This shrinking is primarily due to the lack of recombination, a process that allows chromosomes to repair and maintain themselves. Some researchers believe that the Y chromosome could vanish in a few million years, but others argue that it has developed mechanisms to stabilize itself. Even if the Y chromosome disappears, alternative sex-determining systems could evolve, ensuring the continuation of male lineage.
