Rumors of male chromosome's demise greatly exaggerated, study finds
For millions of year, the male-determining Y chromosome has seen its gene supply shrink from more than 1,000 genes when sex chromosomes first evolved, to what scientists once thought was only a handful of genes, a downward trend predicted to continue until the Y disappeared altogether.
