Genetically speaking, the big difference between men and women is that where women have two X chromosomes, men have one X and one Y. It is surprising that one chromosome difference out of our total of twenty-six can have such an important consequence. Is this relatively small genetic variance really sufficient to explain the differences between the sexes, not just the physical but the psychological, social, even cultural?
Leading geneticist Professor Bryan Sykes takes us on a fascinating exploration into the science of sex and gender, and takes a scientific look at what makes men tick. His conclusions will surprise some people and are bound to cause controversy. His research has shown that the all-important male Y chromosome is getting smaller and the female X chromosome is taking over. Women are winning the evolutionary battle of the sexes. The result is that men, slowly but surely, are heading for extinction...
