Y, the fuss...?!

The Y chromosome is all set to become extinct, but not until a million years from now...

Man’s experiments with science and nature have always left us spellbound. Ranging from test-tube babies to proving the fact that women could probably reproduce without a man, little did we know that these finds would not just be handy, but crucial in the times to come... According to a new research, the Y chromosome, which a man carries, may get extinct in about a million years. But there’s no need to press the panic button just yet. “It’s just a hypothesis as of now and there is no certainty and confirmation,” says Dr. Vinant Bhargava.

Human beings reproduce with the help of both the sexes unlike the likes of hermaphrodite earthworms, which have no such requirement (they can reproduce without the males). But for us, the male needs to fertilise the female egg in order to reproduce. The females carry only the X chromosome, but the males carry both X and Y chromosomes; the Y chromosome being responsible for the birth of boys. It’s an irony that even though these facts state that only males are responsible for the birth of a baby boy, still in a country like ours, the women are squarely blamed for not giving birth to male children; even though she is biologically incapable of doing so without the help of a male. It’s a fact that “the Y chromosome travels faster than the X chromosome, but it also has a shorter lifespan,” asserts Dr. Vinant Bhargava. But in the light of the hypothesis and the research, it’s a matter of great concern for the medical fraternity and us as to how this scenario would be handled. Will the male population vanish in a million years? Will there be another form of chromosome adopting the role of the Y chromosome? Or will nothing happen at all?
