Men are doomed by their mothers – because women pass on genetic flaws which may explain why males die sooner, research suggests.
Scientists said there is increasingly compelling evidence to show that men are the weaker sex, because DNA passed on from their mothers can cause damage to male health.
A series of studies show that certain types of mutations only have negative consequences when passed from women to their sons.
Genetics experts dubbed the phenomenon “mother’s curse” – and said the theory could explain why men have an overall shorter life expectancy than women.
They say that in some respects men are a “evolutionary cul de sac” – because they can inherit such flaws yet do not pass them on.
The impact of defective mitochondrial DNA could affect men’s health in several ways, researchers suggested, increasing the risk of several diseases, of the heart, muscles and nerves.
