Hey Presto!

A simple genetic “flick switch” can transform female ovary cells into male testicular ones according to scientists who have been experimenting on mice. “The battle of the sexes is a never-ending war waged within ourselves as male and female elements of our own bodies continually fight each other for supremacy. This is the astonishing implication of a pioneering study showing that it is possible to flick a genetic switch that turns female ovary cells into male testicular tissue. For decades, the battle of the sexes has been accepted by biologists as a real phenomenon with males and females competing against each other – when their interests do not coincide – for the continued survival of their genes in the next generation. Now scientists have been able to show that a gender war is constantly raging between the genes and cells of one individual.”
