Y Chromosome Fading: Impact on Future of Mankind —
Have you ever wondered what makes a man? It all depends on the Y chromosome. This tiny piece of DNA determines the sex of a human male. But scientists are growing concerned: The Y chromosome is shrinking.
Could this mean the end of man? And what it will mean for the future of mankind?
What is the Y chromosome?
The two sex chromosomes in humans is the ‘Y chromosome’ & the other is the ‘X chromosome’. Females have two X chromosomes (XX), while males have one ‘X chromosome’ & ‘Y chromosome’ (XY). The ‘Y chromosome’ carries the genes that develop ‘Male’ characteristics…

The ‘Y chromosome’ is much smaller than the ‘X chromosome’… In fact, it is the smallest human chromosome. Over millions of years, it has lost its genes & became rare… Some scientists believe that if this trend continues, then Y chromosome could disappear altogether.
Is the Y chromosome really gone?
The idea that the Y chromosome is disappearing is not just science fiction. Studies have shown that the Y chromosome has lost genes over millions of years.
At one point it had as many genes as the X chromosome, but now it has only a fraction of that number left. Some…
