According to a new research from genetics gurus, the Y chromosome that all men carry is not at all hobbled by its missing bit.
For those who don't know, men carry the XY chromosome pair, while women carry two X chromosomes.
The bloke-osome is thought to have evolved from the X, with bits dropping off during 300 million years of evolution. This led to a theory known at the "rotting Y", which said that men would eventually become extinct as their rubbish chromosome falls to pieces.
But Whitehead Institute Director David Page begs to differ. He and his team at the MIT-linked lab in the US have spent the past decade standing up for blokes – and insisted that the unfairer sex has a long time left on this planet (war, mass suicide and grey goo scenarios not withstanding).
Moreover, they found the same genes in five more other mammals: the marmoset, mouse, rat, bull, and 'possum.
