London: In a historic feat, scientists have accomplished the complete decoding of the Y chromosome, a pivotal discovery poised to reshape our comprehension of sex evolution and the intricate development of disorders ranging from infertility to cancer.
The Y chromosome, markedly smaller than its counterpart, the X chromosome, houses a mere 50 genes, a stark contrast to the X chromosome's expansive portfolio of 2,000 genes. Yet, its role is indispensable in male development, hosting the genes orchestrating male sex determination and sperm production.
This monumental breakthrough, marking the full decoding of the Y chromosome, was orchestrated by a global consortium of researchers led by the University of Cambridge in the UK. Employing the cutting-edge technique of whole-genome sequencing, the team meticulously analyzed the DNA of the Y chromosome extracted from the genetic makeup of 100 male subjects.
