Allowing females to mate with multiple males, rather than just one, could help make species more resistant to extinction, University of East Anglia research shows. A new study reveals that when females have multiple males to mate with, their offspring inherit significantly fewer harmful genetic mutations. This, in turn, makes the entire population healthier and less likely to die out.
