Female sheep prefer to mate with submissive males than dominant ones when given a choice, a new study has revealed.
While dominant rams usually mate more often than low-ranking males, they can actually run out of sperm, according to the researchers from the University of the Republic of Uruguay.
What s more, if the dominant rams fathered all the lambs in their flock, there would be less genetic diversity, increasing the risk of malformations and disease within the group.
To counteract this issue, ewes have taken matters into their own hands (well, hooves), by turning to the more submissive males in the group.
